v0.55.1 - improved docs, pytest teardown

A point release focused on a pytest-plugin cleanup fix, a new Sphinx extension for documenting pytest fixtures, and a docs-stack migration to gp-sphinx.

Highlights

Fix: pytest_plugin leaks tmux socket files on teardown (#661, fixes #660)

The server and TestServer fixtures now unlink(2) the tmux socket from /tmp/tmux-<uid>/ during teardown, in addition to calling server.kill(). tmux does not reliably remove its own socket on non-graceful exit, so /tmp/tmux-<uid>/ would accumulate stale libtmux_test* entries across runs — 10k+ observed on long-lived dev machines.

A new internal _reap_test_server helper centralizes the kill + unlink flow and suppresses cleanup-time errors, so a finalizer failure can no longer mask the real test failure.

If you use libtmux's pytest plugin in CI or locally, upgrade to stop the leak.

New: Sphinx extension for pytest fixture documentation (#656)

A new Sphinx extension (docs/_ext/sphinx_pytest_fixtures.py) renders pytest fixtures as first-class API documentation with scope/kind/factory badges, cross-referenced dependencies, and auto-generated usage snippets.

• .. autofixture:: — autodoc-style documenter for individual fixtures
• .. autofixtures:: — bulk discovery and rendering from a module
• .. autofixture-index:: — auto-generated index table with linked return types (via intersphinx) and parsed RST descriptions
• :fixture: cross-reference role with short-name resolution
• Scope, kind, and autouse badges with touch-accessible tooltips
• Responsive layout (mobile metadata stacking, badge font scaling, scroll wrappers)
• WCAG AA contrast compliance in both light and dark mode
• 109 tests (unit + integration)

Also fixes an inaccurate session_params fixture docstring surfaced by the new extension.
