fix(cli): handle Supervisor key releases and command-search input

[luokerenx4]

The CLI Supervisor handled Kitty key release events in its raw input listener before pi-tui's focused-component release filter. A Down press followed by release moved selection twice, and an Esc release could detach after its press closed Commands. Consume releases at the Supervisor input boundary while preserving press/repeat behavior.

Command search now matches enhanced Backspace and Ctrl+U sequences and accepts complete bracketed paste as single-line search text. Pasted control sequences remain rejected and pasted text does not execute shortcuts. The generic Workspace xterm, WebSocket/IPC, and PTY transport are unchanged.

Validation:

• CLI typecheck and git diff --check passed.
• All three Supervisor test files passed: 157 tests, including real pi-tui framing/matching/modal routing and an actual PTY regression that negotiates Kitty flags, pastes into Commands, closes with Esc press/release, and proves the session remains usable.
• The four new protocol tests fail on the untouched dev baseline and pass with this fix.
• Full CLI package suite passed with a test-subprocess umask of 022: 76 files passed, 789 tests passed, 1 skipped. The earlier installer assertion failure was caused by this environment's inherited umask 0077: the fixture's default-created index.html already had mode 0600, so chmod(0600) did not alter it. The same assertion passes on untouched dev under umask 022. No system security settings or installer production code were changed.
• Exact head ec43142 passed Dev PR Clean Build #369: CI workflow contracts and complete workspace build succeeded. Vercel status also succeeded.
• Local PTY testing required compiling the installed node-pty source against Node-API headers because the environment proxy blocks nodejs.org header downloads. Native Windows PTY execution was not tested.

Based on dev commit 48cdb0f, including notification PR #1668. Draft for review; no merge or release.
