chore(release): update package version to 1.0.62

* Implement tests for inserting, updating, and retrieving UUIDs in a SQLite database.
* Verify that Value() returns a string representation of the UUID.
* Ensure compatibility with custom types implementing fmt.Stringer.
* Update type mapper imports to reflect new package path.

+## Nullable Types (`pkg/sqltypes`)
+
+The `bun` and `gorm` writers can generate model structs using
+[`pkg/sqltypes`](./pkg/sqltypes/README.md) — nullable types (`SqlString`,
+`SqlInt32`, `SqlTimeStamp`, `SqlStringArray`, …) that implement
+`database/sql.Scanner`, `driver.Valuer`, and JSON/YAML/XML marshalling in one
+type, selected via `--types sqltypes`. See the
+[`pkg/sqltypes` README](./pkg/sqltypes/README.md) for the full type
+reference, or the [`bun`](./pkg/writers/bun/README.md) /
+[`gorm`](./pkg/writers/gorm/README.md) writer docs for the `--types` flag
+(`sqltypes`, `stdlib`, or `baselib`).

+# sqltypes
+
+Nullable SQL types for hand-written or generated Go models. Each type wraps a
+value with a `Valid` flag and implements `database/sql.Scanner`,
+`driver.Valuer`, `encoding/json`, `gopkg.in/yaml.v3`, and `encoding/xml`
+marshalling — so a single struct field can be scanned from a database row,
+round-tripped through JSON/YAML/XML, and written back to the database without
+any per-format glue code.
+
+This package is what the `bun` and `gorm` writers emit when generating models
+with `--types sqltypes` (see [`pkg/writers/bun`](../writers/bun/README.md) and
+[`pkg/writers/gorm`](../writers/gorm/README.md)). It can also be imported
+directly in hand-written models.
+
+## Import
+
+```go
+import sql_types "git.warky.dev/wdevs/relspecgo/pkg/sqltypes"
+```
+
+## Scalar types
+
+All scalar types are instantiations of the generic `SqlNull[T]`:
+
+| Type | Underlying | Typical SQL type |
+|---|---|---|
+| `SqlInt16` | `int16` | `smallint` |
+| `SqlInt32` | `int32` | `integer` |
+| `SqlInt64` | `int64` | `bigint` |
+| `SqlFloat32` | `float32` | `real`, `float4` |
+| `SqlFloat64` | `float64` | `double precision`, `numeric`, `decimal`, `money` |
+| `SqlBool` | `bool` | `boolean` |
+| `SqlString` | `string` | `text`, `varchar`, `char`, `citext`, `inet`, `cidr`, `macaddr` |
+| `SqlByteArray` | `[]byte` | `bytea` (base64-encoded in JSON/YAML/XML) |
+| `SqlUUID` | `uuid.UUID` (`github.com/google/uuid`) | `uuid` |
+
+You can also instantiate `SqlNull[T]` directly for any type not covered
+above, e.g. `SqlNull[MyEnum]`.
+
+### Date/time types
+
+Plain `time.Time` doesn't distinguish date-only, time-only, and timestamp
+semantics, and its zero value marshals to a confusing `0001-01-01T00:00:00Z`.
+These wrapper types fix both problems:
+
+| Type | Format | Notes |
+|---|---|---|
+| `SqlTimeStamp` | `2006-01-02T15:04:05` | Full timestamp |
+| `SqlDate` | `2006-01-02` | Date only |
+| `SqlTime` | `15:04:05` | Time only |
+
+Zero/pre-epoch values (`time.Time{}` or anything before `0002-01-01`) marshal
+to `null` and `Value()` returns `nil`, instead of leaking Go's zero-time
+sentinel into the database or API responses.
+
+### JSON types
+
+| Type | Underlying | Notes |
+|---|---|---|
+| `SqlJSONB` | `[]byte` | Raw JSON bytes; `MarshalYAML` decodes to native YAML mappings/sequences instead of an embedded JSON string |
+| `SqlJSON` | `= SqlJSONB` | Alias — PostgreSQL's `json` and `jsonb` share the same Go representation |
+
+`SqlJSONB` has `AsMap()` / `AsSlice()` helpers for pulling out
+`map[string]any` / `[]any` without a separate `json.Unmarshal` call.
+
+### Vector type (pgvector)
+
+`SqlVector` wraps `[]float32` for the `vector` column type ([pgvector](https://github.com/pgvector/pgvector)),
+scanning/writing the `[1,2,3]` literal format pgvector uses over the wire.
+
+## Array types
+
+PostgreSQL array columns (`text[]`, `integer[]`, …) map to `SqlXxxArray`
+types, each wrapping `Val []T` + `Valid bool` and handling PostgreSQL's
+`{a,b,c}` array literal format on `Scan`/`Value`:
+
+`SqlStringArray`, `SqlInt16Array`, `SqlInt32Array`, `SqlInt64Array`,
+`SqlFloat32Array`, `SqlFloat64Array`, `SqlBoolArray`, `SqlUUIDArray`.
+
+## Constructing values
+
+Every type has a `NewSqlXxx(v)` constructor that sets `Valid: true`:
+
+```go
+name := sql_types.NewSqlString("Ada Lovelace")
+age  := sql_types.NewSqlInt32(36)
+tags := sql_types.NewSqlStringArray([]string{"engineer", "mathematician"})
+```
+
+The zero value of any type (`sql_types.SqlString{}`) is null/invalid — use it
+directly for a `NULL` field instead of a separate constructor.
+
+Generic helpers:
+
+```go
+sql_types.Null(v, valid)      // SqlNull[T]{Val: v, Valid: valid}
+sql_types.NewSql[T](anyValue) // best-effort conversion from any Go value
+```
+
+## Reading values back
+
+Each scalar type has typed accessors that return the zero value instead of
+panicking when `Valid` is false:
+
+```go
+n.Int64()   // SqlInt16/32/64, SqlFloat32/64, SqlBool, SqlString → int64
+n.Float64() // → float64
+n.Bool()    // → bool
+n.Time()    // SqlNull[time.Time]-based types → time.Time
+n.UUID()    // SqlUUID → uuid.UUID
+n.String()  // fmt.Stringer — empty string when invalid
+```
+
+## Example
+
+```go
+type User struct {
+    ID        sql_types.SqlUUID        `json:"id"`
+    Name      sql_types.SqlString      `json:"name"`
+    Tags      sql_types.SqlStringArray `json:"tags"`
+    Metadata  sql_types.SqlJSONB       `json:"metadata"`
+    CreatedAt sql_types.SqlTimeStamp   `json:"created_at"`
+}
+
+u := User{
+    ID:        sql_types.NewSqlUUID(uuid.New()),
+    Name:      sql_types.NewSqlString("Ada Lovelace"),
+    Tags:      sql_types.NewSqlStringArray([]string{"engineer"}),
+    CreatedAt: sql_types.SqlTimeStampNow(),
+}
+// Metadata left as the zero value → serializes as null, scans as NULL.
+```
+
+Every type implements `sql.Scanner` and `driver.Valuer`, so these fields can
+be used directly as struct fields with `database/sql`, `bun`, or `gorm`
+without additional tags or hooks.

+Plan 9 is supported on a limited basis. The Plan 9 backend opens `/dev/cons` for I/O, enables raw mode by writing `rawon`/`rawoff` to `/dev/consctl`, watches `/dev/wctl` for resize notifications, and then constructs a **terminfo-backed** `Screen` (so `NewScreen` works as on other platforms). Typical usage is inside `vt(1)` with `TERM=vt100`. Expect **monochrome text** and **no mouse reporting** under stock `vt(1)` (it generally does not emit ANSI color or xterm mouse sequences). If a Plan 9 terminal supplies ANSI color escape sequences and xterm-style mouse reporting, color can be picked up via **terminfo** and mouse support could be added by wiring those sequences into the Plan 9 TTY path; contributions that improve terminal detection and broaden feature support are welcome.

-# Ukraine, Russia, and a World Tragedy
-
-## A message to those inside Russia
-
-### Written March 4, 2022.
-
-It is with a very heavy heart that I write this.  I am normally opposed to the use of open source
-projects to communicate political positions or advocate for things outside the immediate relevancy
-to that project.
-
-However, the events occurring in Ukraine, and specifically the unprecedented invasion of Ukraine by
-Russian forces operating under orders from Russian President Vladimir Putin compel me to speak out.
-
-Those who know me, know that I have family, friends, and colleagues in Russia, and Ukraine both.  My closest friends
-have historically been Russian friends my wife's hometown of Chelyabinsk.  I myself have in the past
-frequently traveled to Russia, and indeed operated a software development firm with offices in St. Petersburg.
-I had a special kinship with Russia and its people.
-
-I say "had", because I fear that the actions of Putin, and the massive disinformation campaign that his regime
-has waged inside Russia, mean that it's likely that I won't see those friends again.  At present, I'm not sure
-my wife will see her own mother again.  We no longer feel it's safe for either of us to return Russia given
-actions taken by the regime to crack down on those who express disagreement.
-
-Russian citizens are being led to believe it is acting purely defensively, and that only legitimate military
-targets are being targeted, and that all the information we have received in the West are fakes.
-
-I am confident that nothing could be further from the truth.
-
-This has caused many in Russia, including people whom I respect and believe to be smarter than this, to
-stand by Putin, and endorse his actions. The claim is that the entirety of NATO is operating at the behest
-of the USA, and that the entirety of Europe was poised to attack Russia. While this is clearly absurd to those
-of us with any understanding of western politics, Russian citizens are being fed this lie, and believing it.
-
-If you're reading this from inside Russia -- YOU are the person that I hope this message reaches.  Your
-government is LYING to you.  Of course, all governments lie all the time.  But consider this.  Almost the
-entire world has condemned the invasion of Ukraine as criminal, and has applied sanctions.  Even countries
-which have poor relations with the US sanctioning Russia, as well as nations which historically have remained
-neutral.  (Famously neutral -- even during World War II, Switzerland has acted to apply sanctions in
-concert with the rest of the world.)
-
-Ask yourself, why does Putin fear a free press so much, if what he says is true?  Why the crack-downs on
-children expressing only a desire for peace with Ukraine?  Why would the entire world unified against him,
-if Putin was in the right?  Why would the only countries that stood with Russia against
-the UN resolution to condemn these acts as crimes be Belarus, North Korea, and Syria?  Even countries normally
-allied to Russia could not bring themselves to do more than abstain from the vote to condemn it.
-
-To be clear, I do not claim that the actions taken by the West or by the Ukrainian government were completely
-blameless.  On the contrary, I understand that Western media is biased, and the truth is rarely exactly
-as reported.  I believe that there is a kernel of truth in the claims of fascists and ultra-nationalist
-militias operating in Ukraine and specifically Donbas.  However, I am also equally certain that Putin's
-response is out of proportion, and that concerns about such militias are principally just a pretext to justify
-an invasion.
-
-Europe is at war, unlike we've seen in my lifetime.  The world is more divided, and closer to nuclear holocaust
-than it has been since the Cold War. And that is 100% the fault of Putin.
-
-While Putin remains in power, there cannot really be any way for Russian international relations to return
-to normal. Putin has set your country on a path to return to the Cold War, likely because he fancies himself
-to be a new Stalin.  However, unlike the Soviet Union, the Russian economy does not have the wherewithal to
-stand on its own, and the invasion of Ukraine has fully ensured that Russia will not find any friends anywhere
-else in Europe, and probably few places in Asia.
-
-The *only* paths forward for Russia are either a Russia without Putin (and those who would support his agenda),
-or a complete breakdown of Russian prosperity, likely followed by the increasing international conflict that will
-be the natural escalation from a country that is isolated and impoverished. Those of us observing from the West are
-gravely concerned, because we cannot see any end to this madness that does not result in nuclear conflict,
-unless from within.
-
-In the meantime, the worst prices will be paid for by innocents in Ukraine, and by young Russian mean
-forced to carry out the orders of Putin's corrupt regime.

-and to recognize when that leadership is no longer acting in interest of the country or its people.
