v1.5.4 — docs + packaging refresh
Documentation and packaging refresh (no API change).
- README (also the PyPI project page) and docs streamlined and optimized to render cleanly on narrow / mobile screens: wide tables restructured into readable lists, long code lines wrapped, dense diagrams normalized; verified-Linux CI support stated plainly.
- A Ruff lint gate (import-sort, pyflakes, bugbear) runs in CI as a green ratchet, plus an MCP tool-registration smoke job.
- Release builds run through a pinned, hash-checked composite build action for reproducible sdists and wheels.
