Add three pre-pack validators to catch common runtime failures early:
- validateEntryPoint: checks file exists, extension matches server type,
binary has executable bit (Unix)
- validateCommandVariables: scans mcp_config for unrecognized ${...}
variables against the runtime allowlist
- validateSensitiveFiles: warns about credentials.json, *.pem, *.key,
.ssh/, etc. that would be bundled
validateManifest() now accepts optional { projectDir } to separate the
manifest directory from the source file directory.

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 McpbManifestAny and Logger types from types.js
- Export McpbSignatureInfo and McpbUserConfigValues from shared/common.ts
- Add exports to both main and browser entry points
- Bump version to 2.0.1
This eliminates the need for manual type inference in consuming code.

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

The buildManifest function signature has the localization parameter
commented out (expecting 13 params), but the function call was still
passing it as the 14th argument, causing a type error.

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.
The build script was still importing from the deleted schemas/latest.js file.
Updated to import McpbSignatureInfoSchema from 0.3.js and removed the
mcpb-manifest-latest entry from versionedManifestSchemas.
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.

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.

- 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.

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.
