fix: prevent infinite loop when Claude comments on issues #27

Fixed critical bug where Claude's own comments would trigger re-execution,
causing an infinite loop. Changed logic in client/src/index.ts to skip
processing when Claude is the pusher for issue_comment events.

The fix checks if commentBody is present (indicating an issue_comment event)
and if pusher is 'claude', then skips execution to prevent loops.

This allows Claude to work on issues assigned to it while preventing
comment recursion.
