Two related fixes to the raw-mode controller, mirroring Ink's split
(App.tsx:212-224,357):
- Sync input-state clear (P6): on the last useInput release (refs→0), reset the
input parser, clear the pending escape-flush timer, and detach the stdin
listeners SYNCHRONOUSLY — only the terminal raw-mode toggle stays deferred.
Previously everything was deferred in one microtask, so a same-tick useInput
SWAP (old unmounts → refs 0 → queued; new mounts → refs 0→1; the queued reset
then short-circuits on refs>0) left the parser un-reset and a partial escape
buffered before the swap leaked into the replacement handler. Ink's
clearInputState runs synchronously and unconditionally so this can't happen.
- Force raw-off (P7): the final disable now unconditionally setRawMode(false),
matching Ink's disableRawMode. The previous prevRaw-restore re-captured
stdin.isRaw at acquire while raw was still active on a sync false→true→false
swap, snapshotting `true` and leaving the terminal in RAW mode after exit. No
test locked the prevRaw-restore (an undocumented vue invention), so the field
is removed entirely — eliminating the corruption and aligning with Ink.
The swap-keeps-raw-on behavior (deferred toggle short-circuits on refs>0) is
preserved. Tests lock the partial-escape no-leak on swap and the terminal being
restored (final setRawMode is false) via an isRaw-tracking stdin.
