* feat: keep the outer terminal window title in sync with the session
Herdr emulates the terminals in its panes, so an OSC 0/OSC 2 title
written inside a pane stops at Herdr and never reaches the terminal
Herdr itself runs in. That outer title is what window managers read for
title bars, tab bars, and group bars, so it kept showing whatever the
shell or ssh happened to leave behind.
Add `ui.window_title`, rendered from {hostname}, {workspace}, {tab},
{pane}, and {terminal_title}, and push it to the foreground client
whenever it changes. It renders on the server, so {hostname} names the
machine the panes actually run on rather than the machine a thin remote
client runs on, and it is gated on a pending render so an idle loop
never pays for it.
A title is only remembered as delivered once a foreground client takes
it, so the first client to attach is written to rather than skipped.
`client.window_title.set` still wins over the configured title, and
clearing it now hands the title back to `ui.window_title` instead of
only "herdr".
* fix: deliver the outer window title to a newly attached client
ClientConnected assigns the foreground client directly rather than going
through promote_client_to_foreground, so clearing the sent-title cache
there missed the case that matters most: attaching a second terminal to a
running session. The title was usually unchanged, so the sync returned
early and the new terminal kept whatever its shell or ssh had left.
Key the cache on the client that received the title instead of relying on
every foreground assignment to invalidate it.
* perf: keep hidden pane output off the window title path
Output from a hidden or background pane sets needs_render without setting
needs_full_render, and the retained render plan then skips presentation
for it entirely. Syncing the title on needs_render meant every coalesced
hidden-output tick still formatted, sanitized, and allocated a title that
could not have changed, against the hidden-source early exit AGENTS.md
requires.
Every input to the title is app state, which always requests a full
render, so gate on that instead. The one exception is the focused pane's
own terminal title, which arrives through PTY parsing, so ask for a full
render when that changes and the configured title uses it.
* fix: only cache a window title a client writer received
* fix: carry an api set window title across a live handoff
* fix: make outer window title updates event-driven

* fix: center tab labels for symmetric highlight padding
* docs: note centered tab labels in the changelog
* fix: center tab labels by display width, not char count
* feat: add move tab keybind actions
Add optional keys.move_tab_previous/move_tab_next actions that reorder
the active tab one position, wrapping at either end. Reuses the
existing tab.move runtime path that mouse drag reordering already
drives.
* fix: exit navigate mode on single-tab move attempts
* 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
