Sprint 285: poly-everything (steps 1953–1957)

Final Phase 5 sprint: unified polyglot orchestration over 8 languages
(C++, Python, Rust, Go, Haskell, TypeScript, Java, Lisp)

Components:
- PolyglotFunctionMap: (language, functionName) → implementation tag registry
- PolyglotExecutionContext: per-language runtime config (timeout_ms/env/working_dir)
- PolyglotResultAggregator: FunctionResult collection + AggregateReport (pass/fail/duration)
- PolyglotOrchestrator: ties all three; recordResult; runSummary

26/26 tests pass. Phase 5 (The Proof) complete.
