A tab renamed in Ghostty ignores the title tmux sends, so it stops
showing its session name. omo-status focus now clears that override
through Ghostty's set_tab_title action, finding the tab by its terminal
title, so every tab shows its tmux session again.
omo-notify now drives three signals from omo's UserPromptSubmit, Stop
and Notification hooks:
- A sound through afplay, so Focus modes cannot mute it
- A Ghostty notification (OSC 777) written to the session's tmux client
terminal, so clicking it opens the tab it came from. This replaces the
osascript banner, which opened Script Editor's file picker on click
- omo-status markers in front of the tab title: red error, amber
waiting for input, green finished, blue working. A tab shows its most
urgent agent; focusing it clears red, amber and green and selects the
pane that sent the banner
tmux puts @omo_status in the title and runs omo-status on client focus.
