repo hygiene, tooling config, v0.2.0

- Untrack src/ocr_pipeline.egg-info from git, delete pyproject.toml~,
  stale run_008/run_009 dirs
- Ruff config moved to [tool.ruff.lint] (silences deprecation warning)
- Pre-commit: bump revs (ruff v0.14.13, mypy v1.18.1, hooks v6.0.0);
  drop redundant isort hook (ruff I already sorts imports)
- mypy: add ignore_missing_imports for optional deps; types-PyYAML in
  dev extras; python_version=3.12 for numpy 2.5 stubs compat; CI step
- Doctor: suppress paddle ccache UserWarning noise during check
- CHANGELOG dated for 0.2.0; README minimal-style rewrite with
  collapsible details sections
- Bump version to 0.2.0
