Previously, the script only supported extracting regions from `.ts/.tsx`
files using the `#regionName` syntax. Now it also supports including
entire files without a region specifier, enabling sync of any file type
(JSON, YAML, shell scripts, etc.) into documentation.
Changes:
- Make `#regionName` optional in the `source=""` attribute
- Accept any fence language (not just `ts`/`tsx`)
- Simplify cache to flat map with composite keys
- Add validation error for region extraction on non-TypeScript files
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Migrate JSDoc and markdown documentation from `{@includeCode ./file#region}`
tags to inline code fences with `source="./file#region"` attributes.
Code examples are now visible directly in source files while remaining
type-checked via their `.examples.ts` source files.
Add `scripts/sync-snippets.ts` to extract code from `//#region` blocks
and sync it into labeled fences. Run with `npm run sync:snippets`.

* fix: ensure lib is built before examples:build
Add preexamples:build hook to automatically run `npm run build` before
`examples:build`. This ensures examples always type-check against the
latest library code, catching breaking changes during development.

Lower the minimum version of @oven/bun-* optional dependencies from
^1.3.4 to ^1.2.21. This is the lowest common version available across
all platform-specific packages, improving compatibility for contributors
who may not have access to the latest package versions.
The caret range (^) still allows npm to install newer versions when
available.

* feat: add ts-to-zod schema generation from spec.types.ts
Add automated Zod schema generation using ts-to-zod:
- New npm script `generate:schemas` to regenerate schemas from spec.types.ts
- Post-processing script for Zod v4 compatibility and MCP SDK type imports
- src/spec.types.ts: Pure TypeScript interface definitions (source of truth)
- src/schemas.generated.ts: Auto-generated Zod schemas
- src/schemas.ts: Re-exports with PascalCase naming for backwards compatibility
The generated schemas provide a simpler alternative to the hand-written schemas
in types.ts, useful for lighter validation or reference implementations.

* refactor: use ts-to-zod as library with integration tests

- scripts/generate-schemas.ts: New script using ts-to-zod library API
- Detailed documentation of why each post-processing step is needed
- Generates integration tests via getIntegrationTestFile()
- Better error reporting and control
- src/schemas.generated.test.ts: Auto-generated integration tests
- Compile-time verification that schemas match TypeScript types
- Uses expectType<> pattern for bidirectional type checking
- Removed scripts/postprocess-schemas.ts (merged into generate-schemas.ts)
- Fixed McpUiResourceTeardownResult to include index signature for MCP SDK
Protocol compatibility (detected by the new integration tests)
Post-processing rationale (documented in generate-schemas.ts):
1. zod → zod/v4: Explicit v4 subpath for version clarity
2. z.any() → MCP SDK schemas: External types need real validation
3. z.record().and() → z.looseObject(): Index signatures need Zod v4 idiom
