Remove vLatest concept and associated files

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.
