Review round on PR #757. The route turns EVERY upstream failure into
isLlamaSwap: false, so the old line silently promised an unreachable
endpoint was merely mute, and the live-session check missed a null pid
(the PTY exited, the same test keep-warm applies).
- Require pid !== null in _getCustomModelInUseBySession, pinned by a
'process exited' case in the marks-nothing table
- Reword #customModelPickUnknown to claim only that nothing was
reported, true for a down endpoint too; drop the 'stays quiet for a
failed probe' promise from changeset, docs and comments
- architecture-invariants: add the In-use tier, both pin fences
(customModel not displayModel; stopped/null-pid/paneExit never
count) and the unknown-line rule
- Mirror the wording through i18n (key + zh-CN), index.html fixture,
styles.css comment, and the run-menu tests
