refactor: rename logging.py, in-process scheduler, trim .gitignore

- winnow/logging.py → winnow/log_config.py: avoids shadowing the stdlib
  logging module; log file renamed from immich_export.log to winnow.log
- scheduler.py: run main() in-process instead of subprocess.run so
  InsightFace and SigLIP models stay resident in memory across scheduled
  runs (hundreds of MB load, previously reloaded every run)
- .gitignore: replaced 200-line boilerplate with ~30 project-relevant
  patterns; removed Django/Flask/Redis/RabbitMQ/Scrapy/etc. noise
- .python-version: untracked (redundant with requires-python in
  pyproject.toml; kept in .gitignore for local pyenv users)
