Bug: session.list silently omits adapters after fixed 5s discover timeout #73

What happened

When an adapter discover() call is slow/fails, agentctl list can silently exclude that adapter’s sessions.

Expected

List output should indicate partial results (which adapters timed out/failed), not silently drop them.

Repro (code path)

In src/daemon/server.ts, session.list wraps adapter discover calls in a fixed 5000ms timeout and drops rejected results without user-facing warning metadata.

Impact

Users may believe sessions are missing/nonexistent.

Proposed fix

• Include warning metadata in JSON output (e.g. omitted/failed adapters)
• Print non-fatal warnings in table mode
• Consider per-adapter timeout tuning

Environment

• agentctl 1.5.0
