* fix(runtime): align debug-mode unmount byte stream to Ink
In DEBUG mode (non-interactive) vue-tui's teardown emitted neither a final-frame
re-emit nor a trailing newline, while Ink emits both (ink.tsx:749-762 settleThrottle
re-emit + ink.tsx:812-819 `debug ? '\n' : lastOutput + '\n'`). So for a debug app
that renders "Hello" once, Ink's byte stream is "HelloHello\n" but vue-tui's was
just "Hello" — a divergence that matters when porting Ink debug snapshots / CI logs.
- Fire the final-frame re-emit `mountedCommit()` for debug too (was interactive-only).
- In the non-interactive teardown write, emit a bare "\n" for debug (Ink parity),
keeping the non-debug `lastFrame + "\n"` branch byte-identical.
Because the @vue-tui/testing render() helper captures debug commits via an internal
frame sink, gate the debug commit's two `frameSink?.(...)` forwards on
`!teardownStarted` so the teardown re-emit (a stdout byte-parity FLUSH, not a render)
does not append a spurious entry to the helper's live `frames[]`. `teardownStarted`
is set at the top of teardown() before the re-emit, so this covers EVERY teardown
route (unmount / cleanup / exit / Ctrl+C / signal / process.exit). Both `stdout.write`
calls stay unconditional, preserving byte parity.
Adds a PTY byte-parity test (asserts "HelloHello\r\n") and a testing-helper test
covering all teardown routes (frames.length stable, incl. <Static>).

* test: drop CI-fragile exitOnCtrlC frames-teardown case
The Ctrl+C case timed out in CI (waitUntilExit never resolved — stdin/raw-mode
timing is environment-fragile), while passing locally. Ctrl+C routes through the
SAME exit-driven teardown path as programmatic useApp().exit()
(emitInput → appContext.exit() → teardown()), which the remaining exit() cases
already cover, so removing it loses no teardown-route coverage of the
!teardownStarted frame-sink gate.
