feat(stats,tmux): global Σ@window stats across processes with flocked cache; width mitigation (narrow/maxlen); configurable [stats] window_minutes; robust coverage parsing; docs update\n\n- Add internal/stats with windowed event cache + flock + atomic writes\n- Wire stats into LSP/CLI/Tmux Action; tmux shows Σ@window with per-model tail\n- HEXAI_TMUX_STATUS_NARROW and HEXAI_TMUX_STATUS_MAXLEN for width control\n- Add [stats] window_minutes to config and apply on startup\n- Improve Magefile coverage handling; add tests to lift coverage >85%\n- Update docs/tmux.md and config example
