* 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.

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
herdr embeds `libghostty-vt` as a headless terminal emulator per pane,
and its readonly stream handler silently drops `.clipboard_contents`
actions. As a result, any child process that writes OSC 52 to copy to
the system clipboard (for example Amp, which enables mouse reporting
and handles selection internally) has its sequence swallowed before it
can reach the host terminal — the user sees the child's "copied" toast
but the system clipboard is never updated.
This change adds an `Osc52Forwarder` that observes raw PTY bytes in
`process_pty_bytes`, reconstructs completed `ESC ] 52 ; (c|) ; <base64>
(BEL|ST)` sequences (write/clear only — queries are dropped since herdr
has no path to reply to the child), and returns them through the
existing `ProcessBytesResult`. The reader task forwards the bytes to
the main loop via a new `AppEvent::ClipboardWrite`, which is written
to stdout from `handle_internal_event`. Routing through the main loop
keeps stdout writes serialized with `terminal.draw` and the other
existing host-terminal emitters, so the new forwarder does not race
with rendering.
Existing herdr-native selection (mouse drag in panes without mouse
reporting) is unchanged and still writes through `selection::write_osc52`.
