Subject: keep idle workers alive: bump_idle_ttl + KeepAlive heartbeat

Root cause: idalib workers run an idle watchdog (worker_lifecycle.py) that
self-exits after idle_ttl_sec (default 600s) of no requests -- deliberate
resource hygiene for a shared/ephemeral supervisor, wrong for an interactive
TUI. CLI-opened startup binary always gets 600s (no flag).

Fix (both verified against a 12s-TTL session):
- IDAClient.bump_idle_ttl(1e9): re-open (idempotent) re-applies TTL, no upper
  cap -> effectively immortal. Primary fix, call once at startup.
- IDAClient.keepalive()/KeepAlive: background server_health heartbeat resets the
  watchdog; covers adopted sessions too. Safety net.

tests/test_keepalive.py: 4/4 (heartbeat + bump both keep a short-TTL worker
alive past 2x TTL). docs updated with why + fix.
