Fixes DisableAutoConnect semantics

DisableAutoConnect semantics
============================

Scope: governs ONLY the service-Start auto-connect decision. Once the
connection goroutine has been spawned (by any path), the flag is never
consulted again — the retry loop keeps trying to connect until ctx is
cancelled by Down / Stop / Logout.

Cases
-----

1. Service Start + DisableAutoConnect = true
   - No connection goroutine spawned.
   - clientRunning stays false.
   - State set to StatusIdle.
   - Daemon stays passive until an explicit Up RPC.

2. Service Start + DisableAutoConnect = false
   - Spawn connectWithRetryRuns.
   - clientRunning = true.
   - Retry loop runs until ctx cancelled.

3. Up RPC (any value of DisableAutoConnect)
   - Flag ignored. The user / admin explicitly asked to connect — by
     definition not "auto".
   - Spawn connectWithRetryRuns.
   - clientRunning = true.

4. MDM-triggered restart (any value of DisableAutoConnect)
   - Flag ignored. An MDM policy change applies new config to an
     already-running engine; treated as an implicit Up.
   - Spawn connectWithRetryRuns.
   - clientRunning = true.

5. Down / Stop / Logout
   - Cancels ctx → connectWithRetryRuns exits → close(giveUpChan).
   - cleanupConnection clears clientRunning = false.
   - DisableAutoConnect not involved.
Prepare for next step

Collapse error log into s.connect and rename it to more explicit connectOnce
