fix(terminal): address review: Key tester isolates shortcuts, Codex stays on line feed

- app.js: the shortcut dispatcher returns early for events aimed at a data-raw-keys
  field, so Ctrl+W / Ctrl+L / Escape / Alt+1 / Ctrl+K pressed in the Key tester no
  longer kill the session, clear the terminal or close Settings
- stock.ts: drop Codex's esc-enter (a line feed works); no stock CLI declares a chord.
  The esc-enter path is tested through a clis.json override
- tests: unused port (3194), Ctrl+Enter asserts no keypress, shortcut-isolation test
  (verified to fail without the guard)
- docs/comments point at capabilities.newline; set-input class, trailing whitespace

## The newline chord
`capabilities.newline` (`'line-feed'` | `'esc-enter'`, absent = line feed) is the byte sequence the `send-key` route types into the pane for Shift+Enter. A line feed (`0x0a`, also Ctrl+Enter) is what Claude Code's Ink input reads as "insert a newline"; `esc-enter` (`ESC CR`, the Option/Alt+Enter chord) is for a composer that ignores a bare line feed, which Codex does in some terminals (#495). It is an enum rather than a byte string on purpose: config never carries bytes that get typed into a pane. Settings → Terminal & Input → **Key tester** prints what a browser reports for keydown/keypress/keyup, to see whether a device is sending what you think.

No stock CLI declares it today: the bytes are typed by tmux on the server, so the browser's OS cannot change what a CLI reads, and Codex 0.147.0 was checked to take a line feed (a Shift+Enter that submits is the keypress leak fixed in #520, not a byte problem). A user `clis.json` can set it for a CLI that needs it. It is an enum rather than a byte string on purpose: config never carries bytes that get typed into a pane.
