- docs/wiki/The-Dashboard.md: the tab-appearance table gains the exited
state (muted dot plus an `exited (137)` badge) and explains the bare
`exited` variant.
- The detailed sidebar and rail no longer pair the muted dot with an "idle"
pill: an exited session's pill reads "exited" (neutral styling) and its
since stamp measures from the observed exit. This is a label override on
the row model, not a new state, so SESSION_ACTIVITY_RANK and the home
screen order are untouched, and a pending alert still keeps its own pill.
The row signature includes the flag so the incremental path repaints it.
- The exited badge is aria-hidden like its sibling badges, and the exit is
appended to the tab's aria-label in both render paths through one helper.
- test/tmux-manager.test.ts re-adds the junk-trailing-field parser case
against parsePaneRows.
