feat(security): add configurable SQL procedure names

* Introduce SQLNames struct to define stored procedure names.
* Update DatabaseAuthenticator, JWTAuthenticator, and other providers to use SQLNames for procedure calls.
* Remove hardcoded procedure names for better flexibility and customization.
* Implement validation for SQL names to ensure they are valid identifiers.
* Add tests for SQLNames functionality and merging behavior.

+# resolvemcp
+
+Package `resolvemcp` exposes registered database models as **Model Context Protocol (MCP) tools and resources** over HTTP/SSE transport. It mirrors the `resolvespec` package patterns — same model registration API, same filter/sort/pagination/preload options, same lifecycle hook system.
+
+## Quick Start
+
+```go
+import (
+    "github.com/bitechdev/ResolveSpec/pkg/resolvemcp"
+    "github.com/gorilla/mux"
+)
+
+// 1. Create a handler
+handler := resolvemcp.NewHandlerWithGORM(db, resolvemcp.Config{
+    BaseURL: "http://localhost:8080",
+})
+
+// 2. Register models
+handler.RegisterModel("public", "users", &User{})
+handler.RegisterModel("public", "orders", &Order{})
+
+// 3. Mount routes
+r := mux.NewRouter()
+resolvemcp.SetupMuxRoutes(r, handler)
+```
+
+---
+
+## Config
+
+```go
+type Config struct {
+    // BaseURL is the public-facing base URL of the server (e.g. "http://localhost:8080").
+    // Sent to MCP clients during the SSE handshake so they know where to POST messages.
+    // If empty, it is detected from each incoming request using the Host header and
+    // TLS state (X-Forwarded-Proto is honoured for reverse-proxy deployments).
+    BaseURL string
+
+    // BasePath is the URL path prefix where MCP endpoints are mounted (e.g. "/mcp").
+    // Required.
+    BasePath string
+}
+```
+
+## Handler Creation
+
+| Function | Description |
+|---|---|
+| `NewHandlerWithGORM(db *gorm.DB, cfg Config) *Handler` | Backed by GORM |
+| `NewHandlerWithBun(db *bun.DB, cfg Config) *Handler` | Backed by Bun |
+| `NewHandlerWithDB(db common.Database, cfg Config) *Handler` | Backed by any `common.Database` |
+| `NewHandler(db common.Database, registry common.ModelRegistry, cfg Config) *Handler` | Full control over registry |
+
+---
+
+## Registering Models
+
+```go
+handler.RegisterModel(schema, entity string, model interface{}) error
+```
+
+- `schema` — database schema name (e.g. `"public"`), or empty string for no schema prefix.
+- `entity` — table/entity name (e.g. `"users"`).
+- `model` — a pointer to a struct (e.g. `&User{}`).
+
+Each call immediately creates four MCP **tools** and one MCP **resource** for the model.
+
+---
+
+## HTTP / SSE Transport
+
+The `*server.SSEServer` returned by any of the helpers below implements `http.Handler`, so it works with every Go HTTP framework.
+
+`Config.BasePath` is required and used for all route registration.
+`Config.BaseURL` is optional — when empty it is detected from each request.
+
+### Gorilla Mux
+
+```go
+resolvemcp.SetupMuxRoutes(r, handler)
+```
+
+Registers:
+
+| Route | Method | Description |
+|---|---|---|
+| `{BasePath}/sse` | GET | SSE connection — clients subscribe here |
+| `{BasePath}/message` | POST | JSON-RPC — clients send requests here |
+| `{BasePath}/*` | any | Full SSE server (convenience prefix) |
+
+### bunrouter
+
+```go
+resolvemcp.SetupBunRouterRoutes(router, handler)
+```
+
+Registers `GET {BasePath}/sse` and `POST {BasePath}/message` on the provided `*bunrouter.Router`.
+
+### Gin (or any `http.Handler`-compatible framework)
+
+Use `handler.SSEServer()` to get an `http.Handler` and wrap it with the framework's adapter:
+
+```go
+sse := handler.SSEServer()
+
+// Gin
+engine.Any("/mcp/*path", gin.WrapH(sse))
+
+// net/http
+http.Handle("/mcp/", sse)
+
+// Echo
+e.Any("/mcp/*", echo.WrapHandler(sse))
+```
+
+### Authentication
+
+Add middleware before the MCP routes. The handler itself has no auth layer.
+
+---
+
+## MCP Tools
+
+### Tool Naming
+
+```
+{operation}_{schema}_{entity}    // e.g. read_public_users
+{operation}_{entity}             // e.g. read_users  (when schema is empty)
+```
+
+Operations: `read`, `create`, `update`, `delete`.
+
+### Read Tool — `read_{schema}_{entity}`
+
+Fetch one or many records.
+
+| Argument | Type | Description |
+|---|---|---|
+| `id` | string | Primary key value. Omit to return multiple records. |
+| `limit` | number | Max records per page (recommended: 10–100). |
+| `offset` | number | Records to skip (offset-based pagination). |
+| `cursor_forward` | string | PK of the **last** record on the current page (next-page cursor). |
+| `cursor_backward` | string | PK of the **first** record on the current page (prev-page cursor). |
+| `columns` | array | Column names to include. Omit for all columns. |
+| `omit_columns` | array | Column names to exclude. |
+| `filters` | array | Filter objects (see [Filtering](#filtering)). |
+| `sort` | array | Sort objects (see [Sorting](#sorting)). |
+| `preloads` | array | Relation preload objects (see [Preloading](#preloading)). |
+
+**Response:**
+```json
+{
+  "success": true,
+  "data": [...],
+  "metadata": {
+    "total": 100,
+    "filtered": 100,
+    "count": 10,
+    "limit": 10,
+    "offset": 0
+  }
+}
+```
+
+### Create Tool — `create_{schema}_{entity}`
+
+Insert one or more records.
+
+| Argument | Type | Description |
+|---|---|---|
+| `data` | object \| array | Single object or array of objects to insert. |
+
+Array input runs inside a single transaction — all succeed or all fail.
+
+**Response:**
+```json
+{ "success": true, "data": { ... } }
+```
+
+### Update Tool — `update_{schema}_{entity}`
+
+Partially update an existing record. Only non-null, non-empty fields in `data` are applied; existing values are preserved for omitted fields.
+
+| Argument | Type | Description |
+|---|---|---|
+| `id` | string | Primary key of the record. Can also be included inside `data`. |
+| `data` | object (required) | Fields to update. |
+
+**Response:**
+```json
+{ "success": true, "data": { ...merged record... } }
+```
+
+### Delete Tool — `delete_{schema}_{entity}`
+
+Delete a record by primary key. **Irreversible.**
+
+| Argument | Type | Description |
+|---|---|---|
+| `id` | string (required) | Primary key of the record to delete. |
+
+**Response:**
+```json
+{ "success": true, "data": { ...deleted record... } }
+```
+
+### Resource — `{schema}.{entity}`
+
+Each model is also registered as an MCP resource with URI `schema.entity` (or just `entity` when schema is empty). Reading the resource returns up to 100 records as `application/json`.
+
+---
+
+## Filtering
+
+Pass an array of filter objects to the `filters` argument:
+
+```json
+[
+  { "column": "status", "operator": "=", "value": "active" },
+  { "column": "age", "operator": ">", "value": 18, "logic_operator": "AND" },
+  { "column": "role", "operator": "in", "value": ["admin", "editor"], "logic_operator": "OR" }
+]
+```
+
+### Supported Operators
+
+| Operator | Aliases | Description |
+|---|---|---|
+| `=` | `eq` | Equal |
+| `!=` | `neq`, `<>` | Not equal |
+| `>` | `gt` | Greater than |
+| `>=` | `gte` | Greater than or equal |
+| `<` | `lt` | Less than |
+| `<=` | `lte` | Less than or equal |
+| `like` | | SQL LIKE (case-sensitive) |
+| `ilike` | | SQL ILIKE (case-insensitive) |
+| `in` | | Value in list |
+| `is_null` | | Column IS NULL |
+| `is_not_null` | | Column IS NOT NULL |
+
+### Logic Operators
+
+- `"logic_operator": "AND"` (default) — filter is AND-chained with the previous condition.
+- `"logic_operator": "OR"` — filter is OR-grouped with the previous condition.
+
+Consecutive OR filters are grouped into a single `(cond1 OR cond2 OR ...)` clause.
+
+---
+
+## Sorting
+
+```json
+[
+  { "column": "created_at", "direction": "desc" },
+  { "column": "name", "direction": "asc" }
+]
+```
+
+---
+
+## Pagination
+
+### Offset-Based
+
+```json
+{ "limit": 20, "offset": 40 }
+```
+
+### Cursor-Based
+
+Cursor pagination uses a SQL `EXISTS` subquery for stable, efficient paging. Always pair with a `sort` argument.
+
+```json
+// Next page: pass the PK of the last record on the current page
+{ "cursor_forward": "42", "limit": 20, "sort": [{"column": "id", "direction": "asc"}] }
+
+// Previous page: pass the PK of the first record on the current page
+{ "cursor_backward": "23", "limit": 20, "sort": [{"column": "id", "direction": "asc"}] }
+```
+
+---
+
+## Preloading Relations
+
+```json
+[
+  { "relation": "Profile" },
+  { "relation": "Orders" }
+]
+```
+
+Available relations are listed in each tool's description. Only relations defined on the model struct are valid.
+
+---
+
+## Hook System
+
+Hooks let you intercept and modify CRUD operations at well-defined lifecycle points.
+
+### Hook Types
+
+| Constant | Fires |
+|---|---|
+| `BeforeHandle` | After model resolution, before operation dispatch (all CRUD) |
+| `BeforeRead` / `AfterRead` | Around read queries |
+| `BeforeCreate` / `AfterCreate` | Around insert |
+| `BeforeUpdate` / `AfterUpdate` | Around update |
+| `BeforeDelete` / `AfterDelete` | Around delete |
+
+### Registering Hooks
+
+```go
+handler.Hooks().Register(resolvemcp.BeforeCreate, func(ctx *resolvemcp.HookContext) error {
+    // Inject a timestamp before insert
+    if data, ok := ctx.Data.(map[string]interface{}); ok {
+        data["created_at"] = time.Now()
+    }
+    return nil
+})
+
+// Register the same hook for multiple events
+handler.Hooks().RegisterMultiple(
+    []resolvemcp.HookType{resolvemcp.BeforeCreate, resolvemcp.BeforeUpdate},
+    auditHook,
+)
+```
+
+### HookContext Fields
+
+| Field | Type | Description |
+|---|---|---|
+| `Context` | `context.Context` | Request context |
+| `Handler` | `*Handler` | The resolvemcp handler |
+| `Schema` | `string` | Database schema name |
+| `Entity` | `string` | Entity/table name |
+| `Model` | `interface{}` | Registered model instance |
+| `Options` | `common.RequestOptions` | Parsed request options (read operations) |
+| `Operation` | `string` | `"read"`, `"create"`, `"update"`, or `"delete"` |
+| `ID` | `string` | Primary key from request (read/update/delete) |
+| `Data` | `interface{}` | Input data (create/update — modifiable) |
+| `Result` | `interface{}` | Output data (set by After hooks) |
+| `Error` | `error` | Operation error, if any |
+| `Query` | `common.SelectQuery` | Live query object (available in `BeforeRead`) |
+| `Tx` | `common.Database` | Database/transaction handle |
+| `Abort` | `bool` | Set to `true` to abort the operation |
+| `AbortMessage` | `string` | Error message returned when aborting |
+| `AbortCode` | `int` | Optional status code for the abort |
+
+### Aborting an Operation
+
+```go
+handler.Hooks().Register(resolvemcp.BeforeDelete, func(ctx *resolvemcp.HookContext) error {
+    ctx.Abort = true
+    ctx.AbortMessage = "deletion is disabled"
+    return nil
+})
+```
+
+### Managing Hooks
+
+```go
+registry := handler.Hooks()
+registry.HasHooks(resolvemcp.BeforeCreate)   // bool
+registry.Clear(resolvemcp.BeforeCreate)      // remove hooks for one type
+registry.ClearAll()                          // remove all hooks
+```
+
+---
+
+## Context Helpers
+
+Request metadata is threaded through `context.Context` during handler execution. Hooks and custom tools can read it:
+
+```go
+schema    := resolvemcp.GetSchema(ctx)
+entity    := resolvemcp.GetEntity(ctx)
+tableName := resolvemcp.GetTableName(ctx)
+model     := resolvemcp.GetModel(ctx)
+modelPtr  := resolvemcp.GetModelPtr(ctx)
+```
+
+You can also set values manually (e.g. in middleware):
+
+```go
+ctx = resolvemcp.WithSchema(ctx, "tenant_a")
+```
+
+---
+
+## Adding Custom MCP Tools
+
+Access the underlying `*server.MCPServer` to register additional tools:
+
+```go
+mcpServer := handler.MCPServer()
+mcpServer.AddTool(myTool, myHandler)
+```
+
+---
+
+## Table Name Resolution
+
+The handler resolves table names in priority order:
+
+1. `TableNameProvider` interface — `TableName() string` (can return `"schema.table"`)
+2. `SchemaProvider` interface — `SchemaName() string` (combined with entity name)
+3. Fallback: `schema.entity` (or `schema_entity` for SQLite)
