Add UV as a new server type for Python extensions that use UV runtime
for dependency management instead of bundling dependencies.
Schema changes (v0.4):
- Add "uv" to server.type enum
- Make mcp_config optional (not needed for UV type)
- UV extensions rely on pyproject.toml for dependencies
Documentation:
- Add UV runtime section to MANIFEST.md explaining benefits and usage
- Update README.md to recommend UV runtime for Python
- Add complete hello-world-uv example
Benefits of UV runtime:
- Cross-platform support (Windows/macOS/Linux, Intel/ARM)
- Small bundle size (~100 KB vs 5-10 MB)
- Handles compiled dependencies portably
- No user Python installation required
Example manifest:
{
"manifest_version": "0.4",
"server": {
"type": "uv",
"entry_point": "src/server.py"
}
}

Export LATEST_MANIFEST_VERSION to indicate the maximum supported manifest version by the vAny schema. This allows clients to know what the highest version is that they can use.

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.

- Rename CURRENT_MANIFEST_VERSION to LATEST_MANIFEST_VERSION
- Rename CURRENT_MANIFEST_SCHEMA to LATEST_MANIFEST_SCHEMA
- Rename CURRENT_MANIFEST_SCHEMA_LOOSE to LATEST_MANIFEST_SCHEMA_LOOSE
- Update all references throughout codebase and tests
- Add schemas/latest.ts and schemas_loose/latest.ts as aliases to current version
- Update constants.ts to use latest.ts instead of hardcoded version imports
- This makes version updates easier - only need to update latest.ts pointer
- Create src/schemas.ts to re-export from schemas/index.ts for test imports
- Update test manifests to use manifest_version "0.2" instead of "1.0" or "1.0.0"
- Fix import sorting and formatting issues in schema files
- Export McpbManifestSchema from schemas/index.ts
