Bump slice-ansi@9, string-width@8, wrap-ansi@10 and add cli-truncate@6
(both the runtime dep and the pnpm catalog entry for string-width). Rewrite
wrapText truncate variants to delegate to cli-truncate, matching Ink's
wrap-text.ts: grapheme clusters (ZWJ emoji, combining marks) stay whole and
newlines are preserved. Adjust the horizontal-clip left-edge compensation in
paint.ts because slice-ansi@9 drops a straddling wide grapheme whole rather
than splitting it, so lineX must advance by the actually-dropped width.

Adds an early-return guard in paintNode so nodes with DISPLAY_NONE
(already set on their Yoga node) are entirely skipped during paint,
matching Ink's renderNodeToOutput behavior. Without the guard, hidden
text/borders leaked onto visible siblings at x=0.

Codex review found waitUntilRenderFlush gated the scheduler flush on
hasPending() alone, missing the window after schedule() queues a commit
but before the post-flush callback sets hasPendingFlag — letting the
promise resolve before the pending render flushed. Now delegates to
flush() unconditionally; flush() already short-circuits when nothing is
scheduled or pending, so this only adds the missing wait.

Correctness fixes found by max-effort review of the branch diff:
- frame-writer.sync() now updates lastFrame alongside log-update's
previousOutput. Previously the two dedup layers desynced after a sync()
(the clearTerminal path), silently dropping a legitimately-changed frame
and emitting an empty BSU/ESU pair. Adds a regression test.
- scheduler: the queuePostFlushCb callback now bails if scheduled was reset
by cancel(), so a stale callback can't commit on a torn-down tree or
re-arm an uncancellable trailing timer.
- scheduler.flush() now collects multiple concurrent waiters instead of
overwriting a single resolver — fixes a hang when two waitUntilRenderFlush()
calls await the same pending commit.
- render teardown nulls mountedClear so a post-unmount app.clear() can't
write to a torn-down stream.
- test-streams getContentWrites imports bsu/esu instead of hardcoding the
escape literals.

- scheduler.cancel() now resolves a pending flush() waiter, preventing
waitUntilRenderFlush() from hanging when the app unmounts mid-flush
- BSU/ESU now wrap the actual stream writes instead of being embedded in
the frame string, so synchronization survives log-update's incremental
line diffing (matches Ink ink.tsx:1059-1097). Normal branch guarded by
willRender() to avoid empty synchronized-update pairs on unchanged frames

Horizontal clipping now runs per-line AFTER transforms instead of before,
preventing Transform-widened text from escaping clip boundaries. Left-edge
clipping also uses the actual removed width to position subsequent text
correctly when a wide char straddles the boundary.

Absolute-positioned wide characters (CJK, emoji) could paint past the
right edge of a clipped box or the terminal grid, producing output wider
than the column limit. Three fixes:
- Safe-slice after sliceAnsi in clip logic to handle wide char overshoot
- Bounds check in grid write loop to skip chars exceeding grid width
- Width-aware border fill to account for measured corner char widths
* test: add text ANSI sanitization parity tests from Ink (+15)

* test: add use-animation parity tests from Ink (+43)
Port 43 new tests from Ink's use-animation test suite covering:
- Multiple animations in sync, different rates, sibling unmount
- Timer cleanup/recreation on unmount and remount
- Inactive animations, timer leak prevention
- Edge intervals (NaN, Infinity, -Infinity, oversized, zero, negative)
- isActive toggle resets, pause/resume cycles
- Frame catch-up, time/delta tracking, reset() behavior
- Newly mounted/activated animations don't inherit elapsed time
- Wall clock monotonicity, getter function isActive support
Uses selective fake timers (setInterval + performance only) so that
render()'s internal setImmediate still works on real clocks. Fake timer
tests read refs directly to avoid Vue scheduler flush timing issues.

* test: add use-box-metrics/measure parity tests from Ink (+16)
Port 16 missing tests from Ink's use-box-metrics, measure-element, and
measure-text test suites. Fix useBoxMetrics to reset metrics to zeros
when the tracked ref detaches (element unmounts or ref switches to null).
3 tests are skipped because vue-tui's useBoxMetrics uses watchPostEffect
(re-runs only when ref.value changes) rather than Ink's layout-commit
listener pattern, so sibling-content and resize-driven re-measurement
is not yet supported.

* test: add screen-reader parity tests from Ink (+11)
Add 11 screen-reader integration tests covering aria-label substitution on
Text/Box, ANSI styling omission, multiple/nested components, null component,
aria-state variants (busy, disabled, expanded), multi-line roles, and
multiselectable listbox.
Also fix component prop bug: Vue normalizes kebab-case prop names to camelCase
at runtime, so props["aria-label"] was always undefined. Switch Box/Text prop
declarations and access to camelCase (ariaLabel, ariaHidden, ariaRole, ariaState).
Add isScreenReaderEnabled option to renderToString() so tests can exercise
screen-reader output through the component pipeline.

* fix: add layout listener so useBoxMetrics updates on resize and sibling changes
Adds a layout listener mechanism to TuiRoot matching Ink's architecture:
- TuiRoot.layoutListeners Set with addLayoutListener/emitLayoutListeners
- emitLayoutListeners called after every yoga.calculateLayout in commit()
- useBoxMetrics subscribes to layout listeners, diffs values before updating
Enables 4 previously-skipped tests.

- sanitize-ansi.test.ts: convert raw ESC/C1 control chars to \u escapes
- frame-writer.test.ts: import cursor escapes from cursor-helpers instead
of duplicating, add 7 createFrameWriter integration tests
slice-ansi can't split within a ZWJ grapheme cluster, so the retry
loop may never find a result that fits. Return empty string instead
of the oversized result.
Port 9 text-width tests from Ink's test suite covering wide characters
in fixed-width Boxes, CJK width calculation, mixed ASCII+wide chars,
ANSI styled text layout, empty Text siblings, and CJK truncation
(end/middle/start/box-width). Also fix CJK truncation bug where
slice-ansi would overshoot on wide character boundaries.

reset, sync+update, cursor positioning, no-trailing-newline fullscreen

Codex review suggestions:
- Wrap mountedCommit() in try/catch so a crash in the final render
doesn't block teardown cleanup (console restore, yoga detach, etc.)
- Skip final render if scheduler already has a pending commit (matches
Ink's shouldRenderFinalFrame guard, prevents potential <Static> duplication)

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

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's posix_spawnp is blocked in sandboxed environments.
child_process.spawn works everywhere. force-tty.cjs patches

Also fix setRawMode this-binding bug (acquireRawMode on undefined).
72/82 PTY tests now pass. Remaining 10 need timing/assertion fixes.

Port Ink's self-built log-update with standard and incremental rendering
modes, cursor positioning, and sync support. Rewrite frame-writer to use

write/done/clear behavior. Remove the npm log-update dependency (-6
packages).

Register process.once('beforeExit') in waitUntilExit() so TUI apps
that finish naturally (no explicit exit/unmount) clean up before the
event loop drains. Add stdout write barrier in resolveExit() to ensure
all output is flushed before settling the exit promise.
Update testing render helper to await the additional async tick
introduced by the write barrier so early-error detection still works.
