* 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

* feat: switch IME to ASCII in prefix mode on Windows
Extend switch_ascii_input_source_in_prefix to Windows: detect IME state
via WM_IME_CONTROL and toggle to ASCII with SendInput for the Korean IME.
Other IME languages are detected and left unchanged.
refs #1802
* docs: clarify Windows (Korean IME) support for prefix ASCII switching
Follow-up to the Windows prefix ASCII switch, which extended
switch_ascii_input_source_in_prefix to Windows but left the surrounding
text describing macOS only.
- Settings row label: "(macOS)" -> "(macOS/Windows)", plus its test.
- Generalize the Windows behavior wording to "switches the IME to
English (ASCII) input" in the config-reference.json entry and the
model.rs doc comment, and state that Windows support is currently
limited to the Korean IME.
- Add a :::caution aside noting the Korean-IME-only limitation to the
en/ja/zh preview docs, keeping the three translations in sync.
refs #1802
* fix: warn when prefix IME toggle injection is incomplete
SendInput can queue fewer events than requested (for example when blocked
by UIPI), which would otherwise leave the IME silently stuck in ASCII or
native mode. Log a warning with the sent and expected counts so the failure
is diagnosable.
refs #1802
* fix: guard prefix IME restore and correct open-status naming
Address maintainer review on the Windows prefix ASCII switch:
- Restore only when safe: store the foreground window at switch time and,
before toggling back, require that the same window is still focused and
the IME is still in English. This stops restore from toggling another
application or overriding a manual return to Hangul during prefix mode.
- Report injection success from send_vk_tap and only arm restoration when
the initial toggle landed; on a partial injection retry the dropped
key-up so a key is not left logically held down. The injection policy is
split into send_vk_tap_with(inject) so the success, partial, and failure
branches are unit-tested without the real SendInput.
- Correct the WM_IME_CONTROL sub-command naming: 0x0005 is IMC_GETOPENSTATUS
(IME open state), not IMC_GETCONVERSIONMODE. Behavior is unchanged; the
constant, comments, and tests now describe the open-status read.
refs #1802
* fix: bound IME open-status read with a timeout
The prefix IME switch reads IMC_GETOPENSTATUS via WM_IME_CONTROL, which
crosses into the terminal-emulator process. A plain SendMessageW would block
herdr's client thread until that process responds, indefinitely if it hangs.
Read through SendMessageTimeoutW with SMTO_ABORTIFHUNG and a short timeout
instead; on timeout the switch is skipped and restore does nothing, so a hung
host process can no longer freeze prefix-mode entry or exit.

* fix: switch prefix ASCII input source on the foreground client
The macOS prefix ASCII-switch ran in the headless server, whose
TISCopyCurrentKeyboardInputSource read is a stale per-process cache
(refreshed only via a main-run-loop notification the server never pumps),
so prefix could leave the terminal on the wrong input source.
Forward it to the foreground client, like clipboard: sync_prefix_input_source
emits AppEvent::PrefixInputSource as an intent; the server forwards it to the
foreground client and the monolithic app applies it in-process via
RealPrefixInputSource, which pumps its main run loop before the stale TIS read.
Key it on Mode::wants_ascii_input so multi-level prefix commands keep ASCII
until returning to the terminal, and restore the IME for rename text entry.
Adds ServerMessage::PrefixInputSource to the already-unreleased protocol 15.
refs #774
* fix: keep prefix input-source switch out of the headless server process
An App-internal drain (the exhaustive drain at the top of
handle_api_request, reachable from prefix-key runtime mutations) can
consume a queued PrefixInputSource intent before the server's
forwarding drain sees it, applying the TIS switch in the headless
server process and stranding the restore state. Gate the in-process
switch on App.local_input_source_switch, disabled by the headless
server alongside the other local side effects, so a swallowed intent
degrades to a skipped switch. Widen the forwarding-bypass maintenance
test to the handle_internal_event_with_prefix_sync wrapper.
