fix(claw): warn if OpenClaw is running before migration

Add _is_openclaw_running() and _warn_if_openclaw_running() to detect
OpenClaw processes (via pgrep/tasklist) before hermes claw migrate.
Warns the user that messaging platforms only allow one active session
per bot token, and lets them cancel or continue.

Fixes #7907
