* fix(runtime): restore terminal on signal exit via signal-exit (Ink parity, G18)
Previously nothing routed a process signal to teardown(): SIGINT-as-signal,
SIGTERM or SIGHUP killed the process with the cursor hidden, the alternate
screen active and raw mode on, leaving the terminal corrupted.
Mirror Ink (ink.tsx:426): register signal-exit's onExit(teardown,
{alwaysLast:false}) at interactive mount, storing the unsubscribe fn, and
call it first thing in teardown() (ink.tsx:765) so the handler is removed on
unmount()/exit() and can't leak or double-run. teardown() stays idempotent
(teardownStarted guard) so a signal-triggered teardown plus a later unmount
won't double-run, and we don't prevent the process from exiting. Only the
live interactive, non-debug mount registers — render-to-string /
non-interactive paths never touch process signal handlers; registration is
guarded against double-registration.
Uses signal-exit v4 (named onExit export; ships ESM + types, so no
@types/signal-exit needed). PTY test sends SIGINT/SIGTERM/SIGHUP to a mounted
alt-screen app and asserts the captured output ends with show-cursor
(\x1b[?25h) + leave-alt-screen (\x1b[?1049l).

Review follow-ups (3 fixes): register signal-exit whenever interactive
(drop the !debug gate so debug-but-interactive apps, which still enter the
alt-screen/hide the cursor, restore on signal — Ink ink.tsx:426); add
!teardownStarted to the registration so a spent app instance does not
re-register on a same-instance remount (the next unmount() returns early at
the teardownStarted guard before it could unsubscribe — a leak); and make
the PTY test prove the SIGNAL drove teardown (fixture never self-unmounts, so
restore bytes can only come from the signal path) with a debug-mode signal
test, an exit-anchored waitForOutput drain, and a bounded retry for the
async-flush race under saturated runners.
Review follow-ups (2 fixes): synchronous restore flush on signal — the
signal-exit teardown path now writes the restore escapes (show-cursor,
leave-alt-screen, disable-kitty) via fs.writeSync to the stdout fd so they
reach the terminal before signal-exit re-raises the signal (a buffered async
stream.write could be lost on abrupt exit); the normal unmount path keeps async
writes. Removed the config-wide retry:3 from vitest.pty.config.ts (it masked
the whole PTY suite) and scoped a retry:2 to the signal-teardown describe only,
for the residual parent-side node-pty onData read-race under a saturated runner.
* chore(parity): ledger — G18 pr-open

The resize handler routed through scheduler.schedule(), deferring the repaint
through the ~32ms commit throttle. Ink's resized() calls onRender() directly,
and a resize is a discrete viewport change that should repaint immediately —
deferring it can leave stale/overlapping content on screen for a frame.
It also made the clearTerminal-on-overflow behavior depend on wall-clock
timing: the #450 "shrink into overflow" test passed only because the throttled
resize emitted ZERO clears (its trailing timer never fired within the test's
nextTicks) and the single clear came entirely from unmount. The test asserted
the right number for the wrong reason, and the dependency on real elapsed time
made it flaky under CPU contention.
Change the resize handler to commit() directly. Now the resize itself emits the
overflow clear deterministically. Update the test to assert the clear happens
ON the resize (clearsAfterResize - clearsBeforeResize === 1) after a single
nextTick — no longer dependent on throttle timing.
The WithChildren shim is only exercised under jsx:"react-jsx", which lives
solely in integration/pty/fixtures/tsconfig.json. Nothing in `ready` ran tsc
against that config (vp check uses jsx:"preserve" and excludes the fixtures;
pty-test only transpiles them), so a regression in the shim — children
silently rejected, or declared props silently widened away — would pass
verification unnoticed.
Add a type-only regression fixture (not a runnable PTY program; not a
*.test.tsx, so vitest never collects it) that pins both directions of the
contract: children are accepted on Box/Text/Static/Transform, and declared
props stay validated via @ts-expect-error (invalid value, wrong type, unknown
prop, and missing required props on Transform/Static).
Wire `tsc -p integration/pty/fixtures/tsconfig.json --noEmit` into `ready` via
a typecheck:fixtures script, run after build (so @vue-tui/runtime resolves
against fresh dist types) and before pty-test, so the react-jsx path is
actually enforced rather than only manually checkable.
Release events now produce empty input to prevent character duplication
when reportEventTypes flag is enabled. key.eventType is still passed
through so handlers can detect release events.

Ink does an explicit onRender() with isUnmounting=true before unmount
(ink.tsx:755-761), which triggers clearTerminal for fullscreen apps.
vue-tui's teardown() was nulling scheduledCommit before unmount, making
shouldClearOnUnmount dead code. Now calls commit() synchronously before
disabling the scheduler, matching Ink's unmount render behavior.
Restores 2 erase PTY tests that were incorrectly attributed to a
React vs Vue rendering difference.

- 2 erase tests: Vue renders a single frame for static content, so
clearTerminal (which requires previousOutputHeight > viewportRows)
never triggers. Ink's React reconciler may produce multiple initial frames.
- 1 rapid arrows test: PTY splits escape sequences across data events,
and the input parser's 20ms pending-escape timer delays processing.

Three runtime bugs and fixture issues fixed:
1. stdin registered both "readable" and "data" handlers, causing double input
processing in real PTY. Now only uses "data" handler (works for both real
TTY and fake PassThrough streams).
2. dispose() didn't call stdin.unref() after restoring raw mode, keeping the
event loop alive and causing raw mode exit tests to hang.
3. PTY fixtures used JSX syntax which tsx compiles without vue-jsx plugin,
producing non-function slot values. Converted to h() with function slots.
Also: term.ts now passes rows arg to node-pty for viewport-dependent tests,
and exit-double-raw-mode fixture uses __READY__ protocol.

node-pty 1.1.0's POSIX_SPAWN_CLOEXEC_DEFAULT flag fails on macOS 26 (Tahoe).
Beta.13 fixes this. Rewrote helpers to match Ink's node-pty architecture,
removed python pty-spawn and force-tty workarounds, added check-pty guard
that skips all 82 tests when node-pty is unavailable.

- CI tests: relax exact count assertions (Vue batches differently from React)
- Mark exit-double-raw-mode as todo (requires real PTY stdin)
- Filter Vue slot warnings from fixture output
- 75/82 PTY tests now pass

node-pty's posix_spawnp is blocked in sandboxed environments.
child_process.spawn works everywhere. force-tty.cjs patches
stdout.isTTY so fixtures behave as if running in a real terminal.
Also fix setRawMode this-binding bug (acquireRawMode on undefined).
72/82 PTY tests now pass. Remaining 10 need timing/assertion fixes.

Fixture files use jsx: react-jsx (via their own tsconfig) and have
expected children type differences. Exclude from package-level checks.

Port console.log and useStdout.write fixtures from Ink to verify
patchConsole and useStdout().write() work correctly in a real terminal.

Tests use run()/term() helpers with real PTY subprocesses.
Note: requires unsandboxed environment for node-pty to spawn.
