NeilandOrca 01bcc8dca2 fix(terminal): claim printable keydowns structurally so committed IME text survives (#13288)
* fix(terminal): show a preedit the IME resumes without a compositionstart

Typing 2-Set Korean shows committed syllables but not the in-progress jamo, so
the user composes each syllable blind. Long-standing hole in the vendored
terminal library, not a regression: the same test fails identically against the
bundle this branch starts from.

The `.active` class that CSS keys `display: block` off is added only in
`compositionstart` and dropped in `_finalizeComposition`. Some IMEs (observed on
Windows/WSL Korean) resume a composition with a bare `compositionupdate` and no
second `compositionstart`, by which point `compositionend` has already hidden the
overlay, so the resumed preedit is written into a hidden element and never
positioned. `updateCompositionElements` also early-returned on `!_isComposing`,
so it would not lay the overlay out either.

Re-show the overlay on an update that carries data, and key the layout guard on
the shown overlay instead. `_isComposing` is deliberately left alone, so no
commit bookkeeping changes and `onData` stays byte-identical. The two guards are
equivalent on every pre-existing path: `compositionstart` sets both,
`_finalizeComposition` clears both.

The bundle hunks are the same two edits applied to the shipped minified output;
the sourcemaps are carried through unchanged.

* test(terminal): prove the resumed-preedit fix against a recorded Windows capture

The synthetic test pins the shape; this replays events a real Microsoft Korean
IME emitted on Windows/WSL. The capture holds three compositionupdates that
resume a composition with no second compositionstart — the exact ordering that
wrote the preedit into a hidden overlay.

Without the fix all three report shown:false; with it all three are visible.
Fixture derived from the sealed 11919-windows-wsl-current capture, which is
read-only and unmodified.

* test(terminal): stop the recorded Hangul fixture pinning a derivation artifact

The capture logs each event twice — a dispatch record and a batched next-frame
re-log. Deriving from both replayed every event twice, which made three
compositionupdates appear to land after a session had ended. Filtered to
dispatch records the capture holds zero resumes and 11 balanced sessions, so
the previous toHaveLength(3) was pinning an artifact of the derivation.

Re-scoped to what the capture does prove: the preedit stays visible across all
37 real updates. Verified by reverting the patch that this passes either way,
so it is coverage and the synthetic test remains the discriminator. Both facts
are now stated in the file.

* fix(terminal): restore the preedit visibility patch onto its own branch

The previous commit accidentally reverted it: checking main's patch and lockfile
into the worktree to test whether a test discriminates also stages them, so the
commit that followed swept them up.

* fix(terminal): claim printable keydowns structurally so committed text survives

* chore(reliability-gates): retarget the IME forwarding gate after the allowlist removal

The gate listed terminal-ime-input-source.test.ts, which went with the
input-source allowlist. Points at the substituted-text commit test instead,
which covers what the gate is actually protecting: text committed outside a
composition session reaching the pty exactly once.

* docs(terminal): record why withholding a claimed keydown needs no timer

The predicate withholds a keydown's byte until the commit arrives, so a key the
IME eats without committing would be dropped. Measured across the recorded
corpus that case does not occur, and the browser marks IME-owned presses on the
keydown itself. Both facts belong next to the predicate rather than only in a
handoff note, since the obvious fix for the imagined gap is a timer, and a timer
here once wrote a newline the user never typed.

* test(terminal): pin the kitty all-keys-as-escape-codes hole explicitly

Flag 8 asks for every printable key as an escape code; this path sends the
committed text raw instead. That is a deliberate trade, not an oversight, but it
was untested — the suite only covered the disambiguate flag. Pinning it makes
the choice visible and records the gate to use if it ever needs closing.

* fix(terminal): keep the kitty key-release report for presses that reached the pty

Claiming the keyup unconditionally suppressed xterm's release report. That was
sized for the old design, which claimed only a short punctuation list; the
structural claim takes every printable keydown, so on macOS an app that
negotiated kitty report_event_types stopped seeing releases for ordinary typing
and would treat every printable key as held down.

Suppress the release only when the press put nothing on the wire — swallowed by
the input source, or owned by a composition transaction. xterm emits nothing
from keyup unless kitty report_event_types (or win32 input mode) is on, so
letting it through is inert everywhere else.
