fix(xray): synchronize lifecycle state (#6138)

* fix(xray): synchronize lifecycle snapshots

Protect process replacement and result caching with a lifecycle state object, so read paths keep one process snapshot while restarts swap state safely. Bound version probing to prevent a stalled binary from holding the restart lock.

* test(xray): cover concurrent lifecycle reads

Exercise status, result, and traffic reads while the managed process is replaced, so the race detector guards the lifecycle snapshot boundary.

* fix(xray): guard process config snapshots

Synchronize hot-applied config snapshots, keep Telegram reads on one lifecycle snapshot, and strengthen lifecycle timeout and concurrency regression coverage.
