fix(sandbox): release local E2B capacity when reconnect confirms the VM is gone (#6547) ...

When Sandbox.connect() fails with a trusted 'sandbox not found' error,
_reconnect_live_client() used to release the deployment-level slot but
still re-raise. _evict_oldest_warm() then treated that confirmed-gone
result like an unknown-state failure: it kept the eviction tombstone and
never called _end_transition_locked(), so the local transitioning slot
leaked on every retry against an already-reaped VM. Once the leaked slots
reach the configured replicas, every acquire rejects or times out with
SANDBOX_CAPACITY_EXCEEDED while active=warm=reserved=0.

Return None from _reconnect_live_client() for trusted gone errors so all
callers (eviction, warm reclaim, discovery, reconciliation) take their
existing already-gone cleanup paths, keeping local bookkeeping consistent
with the deployment-level release on the same signal. Unknown-state
errors (network, auth) still retain the slot for a later retry.

Also report the transitioning count in SandboxCapacityExceededError
details and the wait-timeout message so hidden slot usage is visible
without a restart.

Fixes #6540
