Implemented incremental generation using a file-hash cache to improve performance on large repositories. Added --incremental and --no-cache flags to generate and stats commands. Included serialization/deserialization for ParsedModule and updated .gitignore. Verified with a new test suite and full test run.

Fixes #60


PR created automatically by Jules for task 4925786641500699270 started by @wuzzzzaah

On large repos, re-running `llmstxt-gen generate` parses every file from scratch even when nothing changed. This change introduces a content-hash cache to skip unchanged files.

- Added `cache_path` to `LlmsTxtConfig`.
- Created `src/llmstxt_gen/cache.py` for hashing, persistence, and serialization.
- Updated `src/llmstxt_gen/cli.py` with `--incremental` and `--no-cache` flags.
- Refactored `_collect_modules` to use the cache when incremental mode is active.
- Added `.llmstxt_cache.json` to `.gitignore`.
- Added tests for caching logic and incremental CLI behavior in `tests/test_cache.py`.
