🔄 chore: update schema URL to v0.57.2

[github-actions]

Schema URL Update

Updates the MCP Gateway JSON schema validation URL from v0.57.0 to v0.57.2.

Files Changed

• internal/config/validation_schema.go — schemaURL variable updated to v0.57.2
• internal/config/rules/rules.go — SchemaURL constant updated to v0.57.2
• internal/config/validation_schema_test.go — hardcoded schema URLs updated to v0.57.2

Why

Pinning to a specific release tag ensures reproducible, deterministic configuration validation — the schema won't silently change between runs.

Release Notes

See the gh-aw release notes for changes in this schema version.

The schema pinning comment block is now inconsistent with the actual pinned URL: it still says the schema is fetched from the main branch and lists "Current schema version: v0.50.7". Update this documentation to reflect the pinned version (v0.57.2) and the actual fetch behavior so future updates follow the documented steps correctly.

See below for a potential fix:

	// The schema is fetched from a specific tagged release of gh-aw (a pinned version),
	// not from the main branch. This ensures stable and reproducible validation behavior.
	//
	// To update to a new pinned version:
	//   1. Check the latest gh-aw release: https://github.com/github/gh-aw/releases
	//   2. Update the version tag in the URL below (e.g., vX.Y.Z)
	//   3. Run tests to ensure compatibility: make test
	//   4. Update this comment with the matching version number
	//
	// Current schema version: v0.57.2

The schema URL is duplicated here and in internal/config/rules/rules.go (rules.SchemaURL). To avoid future drift (e.g., error footer linking to a different version than the validator fetches), consider sourcing both from a single constant (for example, have config use rules.SchemaURL or move the URL to a shared constant).

See below for a potential fix:

	//   2. Update the schema URL in rules.SchemaURL to use a version tag instead of main
	//   3. Run tests to ensure compatibility: make test
	//   4. Update related documentation with the version number
	//
	// Current schema version: see rules.SchemaURL
	//
	// Alternative: Embed the schema using go:embed directive for zero network dependency.
	schemaURL = rules.SchemaURL

[Copilot]

SchemaURL is duplicated with config's schemaURL in internal/config/validation_schema.go. Consider centralizing the schema URL in one place so the validation error footer and the schema fetch logic cannot accidentally get out of sync on future bumps.

[Copilot]

This test hardcodes the schema URL string. Since the URL is also defined as rules.SchemaURL (used in the error footer), consider referencing that constant here to avoid needing to update tests separately on every schema bump.
