Changed return type to use the specific v0.2 manifest schema type since the
function returns a manifest with DEFAULT_MANIFEST_VERSION (0.2).

Subject: [PATCH 13/25] Remove vLatest concept and associated files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the concept of "vLatest" throughout the codebase to encourage use of McpbManifestAny which supports all manifest versions. Changes include:

- Delete src/schemas/latest.ts and src/schemas_loose/latest.ts
- Remove vLatest and latest-related exports from schema index files
- Remove McpbManifestLatest type, replace McpbManifest to point to McpbManifestAny
- Remove LATEST_MANIFEST_VERSION, LATEST_MANIFEST_SCHEMA constants
- Update all main export files (index.ts, cli.ts, node.ts) to export from 0.3.js instead of latest.js
- Update tests to use v0_3.McpbManifestSchema explicitly
- Add @deprecated annotation to McpbManifest directing users to McpbManifestAny

This encourages better version compatibility by using the union type that supports all manifest versions rather than assuming a single "latest" version.

Subject: [PATCH 14/25] Make McpbManifest point to v0.2 for backwards
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Change McpbManifest type to point to v0.2 schema instead of McpbManifestAny
- Add DEFAULT_MANIFEST_VERSION export to browser.ts
- Update test fixtures to use manifest_version "0.2" when using McpbManifest type
- Keep @deprecated annotation directing users to McpbManifestAny for multi-version support

This maintains backwards compatibility for existing code using McpbManifest while encouraging new code to use McpbManifestAny for broader version support.

Subject: [PATCH 16/25] Use McpbManifestDefault derived from
 DEFAULT_MANIFEST_VERSION
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes:
- Create McpbManifestDefault type derived from VERSIONED_MANIFEST_SCHEMAS[DEFAULT_MANIFEST_VERSION]
- Update init.ts to use McpbManifestDefault instead of hardcoded v0.2 schema
- Import schema types from version matching DEFAULT_MANIFEST_VERSION (0.2)
- Update test to match commented-out localization field
- Make McpbManifest (deprecated) point to McpbManifestDefault

This makes the codebase more maintainable by deriving types from DEFAULT_MANIFEST_VERSION instead of hardcoding version references.

Changed all entry points (index.ts, cli.ts, node.ts) to export from schemas/index.js
instead of schemas/0.3.js. This provides access to all versioned schemas (v0_1, v0_2,
v0_3, vAny) and VERSIONED_MANIFEST_SCHEMAS without exposing a specific version.

passing it as the 14th argument, causing a type error.

Subject: [PATCH 24/25] Comment out localization parameter in tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The localization parameter is commented out in the buildManifest function
signature, so it should also be commented out in the test calls.
