Closes the renderer half of #88769, found while live-verifying the
profile-lifecycle fixes:
- The secondary-socket reconnect loop now fail-stops when Electron's spawn
guard rejects with "no longer exists" / "is being deleted" — a permanent
condition for that scope, previously retried forever on the 15s-cap
backoff (40+ guard hits observed in 3 minutes after clicking a stale
badge). The entry is disposed, evicted, and the active key restored to
the primary, mirroring the existing missing-connection fail-stop.
- The Bot Mode SDK deleteProfile path now refreshes $profiles after a
successful delete, so the profile rail drops the dead badge instead of
keeping a clickable ghost. (The Desktop dialog path already refreshed
via onDeleted; the SDK path was the gap.)
Tests: two fail-stop regression tests (profile-gone + mid-delete guard
rejections, sabotage-verified to fail without the fix) and a refresh
assertion on the SDK delete ordering test.
