feat(job): declarative YAML job files for named relspec workflows

Add `relspec job list` and `relspec job run <name>` driven by YAML job manifests (relspec.yml / relspec.<name>.yml), so multi-file merge and conversion workflows can be expressed declaratively instead of as long shell command lines. v1 contract (see docs/JOB_FILES.md): - `command` is a closed allow-list (convert, merge, scripts-list); no field accepts a shell string or executable path. - Deterministic discovery: default file first, then named files sorted lexically; all files merged into one namespace; duplicate job names across files are a hard error. - Every path resolves relative to the job file's directory; absolute, home-relative and directory-escaping paths are rejected at validation. - Database credentials referenced by env-var name via `conn_env:`; connection strings are never stored and are redacted from logs/plan. - Full validation (version, unknown fields, command/format, per-command input/output shape, path traversal, depends_on targets, dependency cycles) runs before anything is read, written or executed; per-job pre-flight then checks input existence, script dirs, env vars and the output overwrite policy for the whole plan. - `depends_on` closure runs in deterministic topological order; `--no-deps` runs only the named job. - `--dry-run` (alias `--plan`) prints the resolved plan and exits 0 without touching inputs, outputs or databases. - A failing job propagates the underlying non-zero exit status, logs FAILED (never OK), and writes no success marker. pkg/jobs is side-effect free (discovery/parse/validate/plan only); execution adapters live in cmd/relspec/job.go. Includes unit tests for discovery, validation, planning and path safety, plus CLI tests for end-to-end convert/merge, scripts-list across multiple directories, dry-run, dependency chains, exit-code propagation and log redaction. Deferred: live `scripts execute` from jobs, split/inspect/diff/templ commands, job-to-job output wiring, log rotation/retention. Refs #20 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+	Long: `Run named jobs declared in job files instead of repeating command-line arguments.
+
+A job file is a YAML manifest (relspec.yml, or relspec.<name>.yml for extra
+files) describing one or more jobs. Each job names a RelSpec command plus its
+inputs, output and options:
+
+  version: 1
+  jobs:
+    build-schema:
+      command: convert
+      description: Merge the DBML sources and emit PostgreSQL DDL
+      inputs:
+        - path: schema/core.dbml
+          format: dbml
+        - path: schema/tenant.dbml
+          format: dbml
+      output:
+        format: pgsql
+        path: build/schema.sql
+        overwrite: true
+      options:
+        flatten_schema: false
+      logfile: .relspec/log/build-schema.log
+
+Rules and guarantees:
+  - command is a closed allow-list (convert, merge, scripts-list). Arbitrary
+    shell strings are never executed.
+  - Every path is relative to the directory holding the job file and may not
+    escape it. Absolute and home-relative paths are rejected.
+  - Remote database credentials are referenced by environment-variable name
+    via conn_env; connection strings are never stored in the manifest and are
+    redacted from logs and diagnostics.
+  - Discovery and listing are deterministic.
+  - The whole plan is validated - unknown commands/formats, duplicate job
+    names, missing inputs, path traversal, dependency cycles - before any job
+    runs. Nothing is read, written or executed when validation fails.
+  - A failed job propagates the underlying non-zero exit status and writes no
+    success marker.`,
