- Replace stub module with real code-server module manifest
- Export ParseModulesFromFS(fs.FS) for test isolation (no sync.Once coupling)
- Use sync.OnceValues for the cached loader
- Validate module ID (non-empty, unique), pinned_version, and variable types
during parsing; reject unknown types at load time
- Normalize nil slices to empty in ToSDK() to prevent null in JSON responses
- Distinguish fs.ErrNotExist from other ReadFile errors
- Improve error messages to describe what failed, not internal plumbing
- Rewrite tests with fstest.MapFS fixtures covering all variable types,
default pointer, validation errors, and full SDK field assertions
- Trim zero-value godoc comments
- Add future tense to README for unimplemented behavior; link RFC
