codeman-localandClaude Opus 5 a1c35da0d8 fix(input): deliver a recovered keystroke before the Enter that submits it
Every message typed on an Android phone lost its last character.

An Android soft keyboard commits the last typed character and sends the
Enter key in ONE InputConnection transaction, so the committed-text
`input` event and the Enter keydown are both processed before any
zero-delay timer runs. The orphaned-input recovery from #388 resolved
its candidate only on such a timer, and that lost the character twice
over:

  * ORDER — xterm emits `\r` synchronously from the Enter keydown, and
    the local-echo composer submits `pendingText` right there. The
    recovered character arrived one macrotask too late to be part of the
    prompt.
  * LOSS — that same `\r` bumps the canonical counter, so by the time
    the candidate resolved, `canonicalCount > snapshot` read as "xterm
    spoke for this keystroke" and stood the recovery down. The character
    was not merely late, it was dropped.

Drain pending candidates synchronously at the next keydown instead, from
xterm's custom key handler, which runs before xterm processes that key.
The counter then still holds the value it had while the candidate's own
keystroke was current, so the stand-down decision is made against the
right keystroke, and the recovered byte reaches the composer ahead of
whatever the new key emits. The timer stays as the fallback for a
keystroke with no key after it.

Physical keyboards are unaffected: there the timer has already resolved
the candidate long before the next key arrives.
