deps(libtmux[~=0.55.0]): Bump from ~=0.53.0 for logging, set_title, tmux_bin

why: Pick up three libtmux releases (0.53.1, 0.54.0, 0.55.0) bringing
structured logging, new Pane API, configurable tmux binary, and several
bug fixes that improve error propagation.

what:
- Bump libtmux dependency specifier ~=0.53.0 -> ~=0.55.0 in pyproject.toml
- Update uv.lock (resolved 0.53.1 -> 0.55.0)

libtmux 0.55.0 (2026-03-07):
- Pane.set_title() wraps select-pane -T; pane_title added to format queries
- Server(tmux_bin=) threads custom binary through all commands and version checks
- Pre-execution DEBUG logging in tmux_cmd with structured extra
- TmuxCommandNotFound raised consistently for invalid tmux_bin paths

libtmux 0.54.0 (2026-03-07):
- Structured lifecycle logging (INFO) across Server, Session, Window, Pane
- NullHandler in __init__.py; lazy %s formatting; isEnabledFor guards
- Window.rename_window() now raises on failure instead of swallowing
- Server.kill() captures stderr, handles "no server running" gracefully
- Server.new_session() checks kill-session stderr
- Session.kill_window() target formatting fix (session_name, not window_name)

libtmux 0.53.1 (2026-02-18):
- Fix race condition in new_session() by avoiding list-sessions query
