feat: pre-public cleanup — remove compat shim, add CI, update README

- Remove index.py compat shim: all 10 test files migrated to direct
  db.py calls via conftest.seed_board() helper. test_indexes.py deleted.
- Gitignore .claude/, docs/, CLAUDE.md (local-only files)
- Remove tracked .claude/skills/, CLAUDE.md, docs/ from git
- Add GitHub Actions CI: pytest across Python 3.10-3.13 + ruff lint
- README: update storage references (file-based → SQLite), add board/
  stale/batch commands, update file layout, remove stale limitations,
  remove references to gitignored files
- pyproject.toml: add authors field
- Fix version test to accept 0.3.x

233 tests pass.
