No behavior change. Prepares the split pane's second terminal (and later
grid tiles) to share what today only the primary terminal has:
- _inputSocketFor/_registerInputSocket/_unregisterInputSocket: the
exactly-once input queue, its ACK handling and the redelivery sweep now
deliver over any registered socket bound to a session, not only
this._ws. ACKs are routed by the receiving socket's session; silence is
judged per socket; a stale handle cannot unregister its replacement.
- registerFilePathLinkProvider, cleanedTerminalSelection,
copyTerminalSelection and _handleImagePaste take an optional target
terminal and session (defaults: the primary pane).
- _focusedPane() is the one place to ask which pane the keyboard is in
(primary only, for now); _forEachTile() replaces the _splitPane special
cases in the font, family, weight, skin and resize paths.

A single input over MAX_INPUT_LENGTH (64 KiB) was queued for reliable
delivery, refused by both transports (the WebSocket silently, POST with a
400), and never dropped: the client treated the 400 as transient, so the
frame was re-sent every 2 s forever, blocked every later input for that
session, and came back from localStorage on every reload.
- Client: a paste over the frame limit is split into in-limit frames
(never cutting a surrogate pair) delivered in seq order; over 1 MiB, or
an oversized mux write, it is refused with a toast and never queued.
- Client: the POST drain drops a frame answered 400/413; a WS error ACK
drops it too; frames over the limit persisted by an older build are
pruned on load.
- Server: the WebSocket answers an oversized sequenced frame with
{t:'ia',seq,err:'too_large',max} instead of silence (an older client
reads that as a plain ACK and drops it); the POST schema uses
MAX_INPUT_LENGTH instead of a second 100000 limit.
Verified end to end on an isolated instance: a 110 KB paste reached the
PTY byte-identical over both the WebSocket and the POST path, a poisoned
120 KB persisted frame was pruned on load, and a 2 MB paste showed the
refusal toast with nothing queued.
