refactor: consolidate architecture across 8 issues (A1-A8)
- A1: Extract duplicated PATH discovery to utils.py (single source of truth)
- A2: Convert metadata_reader dataclasses to Pydantic models in models.py
- A3: Simplify get_wrapper() with module-level caching (removed fragile lifespan context)
- A4: Document ILSpyWrapper design rationale (why class exists despite being stateless)
- A5: Document MetadataReader as CPU-bound sync code with thread pool suggestion
- A6: Create constants.py for all timeouts/limits (DECOMPILE_TIMEOUT_SECONDS, etc.)
- A7: Add _compile_search_pattern() helper to deduplicate regex compilation
- A8: Add LanguageVersion validation with helpful error listing valid options
Tests pass, ruff clean.
