Merge pull request #624 from Ark0N/feat/codex-blocked-detection

feat(codex): raise codex approval, question and trust dialogs as BLOCKED

Conflict resolved against #634 in src/session.ts _probePaneWorking():
#624's assignment (a dialog on screen is never work) is kept, and #634's
trust-dialog verdict block (log the hold once, remember the reading)
follows it, before _readWatching().

**`blocked` on `codex` is read off the screen**, because codex has no hooks and is
launched with its approvals on unless `codexConfig.dangerouslyBypassApprovals` is set.
A codex pane showing a command, edit or network approval, a question (`request_user_input`)
or the startup trust prompt raises `blocked` (plus the red alert, push and webhook a Claude
`permission_prompt` raises, alert-only: answer it in the terminal), and the session reads
`idle` while it is up. Unlike a hook, this is a level the server keeps reading, so a wait
for `blocked` that arrives while the dialog is already up answers at once
(`immediate: true`); a wait that did not ask for `blocked` is unaffected. It clears 2 to 4 s
after the dialog leaves the screen. `stop` stays a `400` on codex: nothing on a screen says a
turn ended.
⚠️ **On a `shell` session, only `exit` and marker-matching are dependable.** A shell
