chaithanyak42 7e9824e394 fix(openclaw): dream verification, failed-turn cleanup, atomic lock
1. Write-only verification: only count memory_store, memory_update,
   memory_forget, memory_delete_all as proof of dream execution.
   Removed memory_list (read-only, orient-only pass should not count).
   Scan only the last assistant message (this turn), not the full
   session snapshot, to avoid matching earlier turns' tool calls.

2. Failed-turn cleanup: agent_end now handles dreamSessionId cleanup
   BEFORE the !event.success early return. A failed/aborted turn
   after lock acquisition releases the lock immediately instead of
   waiting for the 1-hour stale timeout.

3. Atomic lock: replaced read-then-write with exclusive create flag
   (wx). Two racing processes: only one succeeds, other gets EEXIST.
   Stale locks are unlinked before the exclusive create attempt.

/**
* OpenClaw Memory (Mem0) Plugin
*
* Long-term memory via Mem0 — supports both the Mem0 platform
* and the open-source self-hosted SDK. Uses the official `mem0ai` package.
*
* Features:
* - 5 tools: memory_search, memory_list, memory_store, memory_get, memory_forget
* (with session/long-term scope support via scope and longTerm parameters)
* - Short-term (session-scoped) and long-term (user-scoped) memory
* - Auto-recall: injects relevant memories (both scopes) before each agent turn
* - Auto-capture: stores key facts scoped to the current session after each agent turn
* - Per-agent isolation: multi-agent setups write/read from separate userId namespaces
* automatically via sessionKey routing (zero breaking changes for single-agent setups)
* - CLI: openclaw mem0 search, openclaw mem0 stats
* - Dual mode: platform or open-source (self-hosted)
