* fix(tui): stop CRLF stdout rendering as blank lines (v2)
Windows child stdout is `\r\n`; the streaming path fed it straight to
`Text.from_ansi`, which treats `\r` as a carriage return and erases each
line's text, so a `[Stdout]` block rendered as a run of blank lines until
the turn finished (the done-state Markdown render strips `\r`). Normalise
`\r\n` -> `\n` before `from_ansi`; lone `\r` is kept so progress-bar
overwrites still work.
* fix(tui): stop leaking empty per-session task_dir signal folders
Both v2 and v3 eagerly `os.makedirs` the per-session `_intervene` /
`_keyinfo` signal dir, but the only writer (`_intervene`) already creates
it lazily — so every session that never used intervene left a stale empty
`temp/_tui_v2_<pid>_<id>` / `temp/_tui_v3_<pid>` behind (85+ accumulated).
`consume_file` tolerates a missing dir, so the eager create is redundant.
- Set only the task_dir *path*; let the writer create it on first inject.
- Remove empty dirs on session close (v2 `_cmd_close`), on graceful exit
(v2 `on_unmount`, v3 `_cleanup`), and sweep stale ones left by crashes
at startup (v2 `on_mount`, v3 `main`). `os.rmdir` only removes empty
dirs, so a still-pending `_intervene` is never clobbered.
* fix(tui): repair /continue search box cursor & up-nav loop (v2)
The SearchablePicker swallowed Right while the search Input had focus
(always treating it as "select"), so the caret could never move right in
the query. And Up could leave the list but never return: from the search
box Down entered the list, yet Up at the top row was stuck.
- Right commits the highlight only when the caret is already at end of the
query; otherwise it moves the caret within the search text.
- Up on the first list row returns focus to the search box (scoped to
/continue — no-op for ChoiceLists outside a SearchablePicker), clearing
the highlight so the next Down re-enters at the first row, not the second.
- Up from the search box wraps around to the bottom of the list.
