fix(mcp): relax library id and name matching

- accept single-segment library ids like /whisper-rtx2080 returned by
  resolve-library-id in get-library-docs
- accept common owner-qualified aliases such as /mozempk/whisper-rtx2080
  when the indexed repo is stored as a single-segment name
- accept single-segment ids with explicit versions such as
  /whisper-rtx2080/v0.0.1
- relax resolve-library-id scoring across separator-only differences so
  queries like whisperrtx2080 still match whisper-rtx2080
- update MCP tool descriptions to document the accepted id formats

Validated with focused regression tests:
- TrueRefMcpToolsTest
- LibraryResolverTest
