Bill d98fc26c05 Sprint 271: LanguageFitnessScorer — polyglot Phase 1 (steps 1883-1887) ...

Add language fitness scoring infrastructure for the polyglot orchestrator.

New components:
- ASTFeatureExtractor.h: extract 5 scalar features from JSON AST subtrees
  (mutation ratio, recursion shape, concurrency primitive, I/O pattern, type complexity)
- LanguageIdiomProfile.h: static ideal feature vectors for 8 languages
  (Python, Rust, Go, Haskell, C++, TypeScript, Elixir, Lisp)
- LanguageFitnessScorer.h: weighted scoring against profiles, returns JSON
  array sorted descending with per-language score and rationale
- RegisterLanguageFitnessTools.h: whetstone_score_language_fitness MCP tool
- Sprint271IntegrationSummary.h: sprint metadata

25/25 tests passing (steps 1883-1887). whetstone_mcp rebuilt with new tool.

Also: merge PROGRESS.md into progress.md (single authoritative log, 15k lines),
update CLAUDE.md to current state (step 1887, sprint 271, 91 tools).
