fix: orphan-processes check only detects Gas Town processes

Changed findRuntimeProcesses() to only detect Claude processes that have
the --dangerously-skip-permissions flag. This is the signature of Gas Town
managed processes - user's personal Claude sessions don't use this flag.

Prevents false positives when users have personal Claude sessions running.

Closes #611
