📝 docs: restructure using Diataxis framework (#489)
The monolithic documentation made it hard for users to find information relevant to their needs — beginners, experienced developers, and API consumers all landed on the same page with no clear path forward. Reorganizes docs into four Diataxis sections: Tutorials (learning), How-to (task-oriented), Concepts (design rationale), and API Reference. Adds comprehensive coverage for previously undocumented features including self-deadlock detection, cancel_check, force release, ReadWriteLock close/SQLite requirements, lifetime expiration, and thread-local behavior differences between sync and async locks. The release pipeline now generates docstrfmt-friendly RST changelog entries. Five Sphinx extensions enhance the reading experience with copy buttons, responsive cards, mermaid diagrams, sitemap, and OpenGraph metadata.

🐛 fix(test): resolve flaky write non-starvation test (#490)
The test only signaled the last reader's release event and relied on chain propagation, but the 3-second join timeout was too tight for PyPy on macOS where process spawn and SQLite operations are slower. Signal all reader release events explicitly and increase the join timeout to 10 seconds to accommodate slower runtimes.

🐛 fix(rw): close sqlite3 cursors and skip SoftFileLock Windows race (#…
…491) ReadWriteLock._configure_and_begin creates cursors via Connection.execute() without closing them. On CPython refcounting destroys them immediately, but on PyPy cursors accumulate until non-deterministic GC collects them. If Connection.__del__ runs first and calls sqlite3_close, a later Statement.__del__ calls sqlite3_finalize on freed memory — segfault. Fix by chaining .close() on every execute() call. Skip test_threaded_shared_lock_obj for SoftFileLock on Windows. SoftFileLock uses file-existence locking where unlink can silently fail under heavy thread contention when an antivirus scanner or search indexer momentarily holds the handle after close(). This orphans the lock file with no recovery path since stale-lock detection is disabled on Windows and PID-based detection cannot distinguish same-process threads. This is the same known limitation already documented by the skip in test_threaded_lock_different_lock_obj.
