feat(tui): prompt queue, history recall, reconnect retry, jump-to-latest (#19)

* feat(tui): queue prompts sent mid-turn and drain on turn end

Pressing enter while a turn runs used to be a silent no-op. Prompts are
now queued (footer shows the count) and auto-sent on done/error; esc
hands queued prompts back to the input instead of firing them into a
cancelled session. A submit while disconnected keeps the draft and
explains why nothing was sent.

* feat(tui): recall submitted prompts with arrow keys

Up on an empty input (or while already walking) steps back through the
session's prompt history; down steps forward and restores the stashed
draft past the newest entry. History is an in-memory ring of 100 with
consecutive duplicates collapsed. With no history to recall, up/down
keep their transcript-scroll behaviour.

* feat(tui): manual reconnect retry and draft-safe disconnects

The terminal disconnected state used to dead-end at 'press ^C to quit'
while typed input was silently swallowed. The footer now offers r to
redial (empty input only, so drafts are never hijacked), a successful
redial flushes queued prompts, and the give-up notice says how to
retry.

* feat(tui): new-output indicator and jump-to-latest key

Scrolled-up scrollback during a run used to give only a muted scroll
percent. The footer now flags new output while busy and advertises G
(also End) to jump to the latest — bound only with an empty input so
typing a capital G or using End for cursor movement is never hijacked.

+Prompts sent while a turn is running are **queued** and sent automatically
+when the turn ends — the footer shows how many are waiting. While the
+transcript is scrolled up mid-run, the footer flags `↓ new output`; press
+`G` to jump to the latest. If the connection drops, bodek retries with
+backoff and, after giving up, keeps your draft and offers a manual retry
+on `r`.
