* fix: page keys scroll pane scrollback at zsh and REPL prompts
PageUp/PageDown were forwarded to the pane whenever DECCKM (application
cursor) was on, assuming only primary-screen pagers enable it, but zsh's
line editor also enables DECCKM, as do REPLs such as python3. The result
was PageUp scrolling shell history instead of Herdr scrollback.
Bracketed paste discriminates the two: it means the app accepts typed or
pasted text at a prompt, so line editors enable it and pagers do not.

* 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.

* 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.
