feat: tmux-agents v1.14.0 opens up to other coding agents
I shipped v1.14.0 of tmux-agents, which adds limited support for other coding agents. Any executable on PATH, such as gemini, opencode or aider, now works wherever tmux-agents takes an agent: tmux-agents start, tmux-spawn and the chain roles. Claude, Codex and Codex profiles keep full features. Other agents get panes, naming, connect, peek, dismiss and tmux-ask messaging, but no automatic tracking, worked time, resume or permission setup, and their first task is sent manually once they reach their prompt. The new docs/agents.md has the feature table and welcomes PRs that add full support for more agents. One behaviour change: a single bare first word to tmux-spawn is now read as the agent to launch.
