* feat: show a zoom indicator in the desktop tab bar
Reserve the right edge of the tab row for a ZOOM pill while the
focused pane is zoomed, matching the accent style of the mode bars.
The per-tab Z suffix stays; the pill makes the zoomed state visible
at a glance like tmux's status-right flag.
* feat: optionally show the hostname in the desktop tab bar
Add ui.tab_bar_hostname to display the machine's hostname at the right
edge of the tab row, like tmux's #h in status-right. The value resolves
where the server renders, so remote sessions show the remote host. Off
by default.
* fix: strip control characters from the tab bar hostname
* fix: hide the hostname when it would squeeze out the tab strip
* feat: add configurable tab bar status
* fix: harden tab bar status updates
* fix: terminate tab bar status process trees
* fix: disable status commands on unsupported platforms
* fix: skip unchanged status command renders
* fix: keep tab bar status opt-in by default

Make herdr persistent by default.
Launching herdr now starts or reattaches to a background session
server. Clients can detach and reattach while panes and agent
processes keep running. Session mode now supports multi-client attach,
auto-detect startup, and a thin-client/headless-server split.
This also refactors the large app, ui, input, pane, config,
workspace, and persistence modules into smaller focused submodules,
while preserving behavior and colocating tests with the code they
exercise.
Upgrade notes:
- persistence mode is now the default
- in-app quit detaches the current client instead of stopping the server
- use `herdr server stop` to stop the background session
- use `--no-session` for the old single-process behavior
- default socket paths now live under the config directory
