fix(session): Auto-accept Claude bypass permissions warning dialog

When Claude starts with --dangerously-skip-permissions, it shows a warning
dialog requiring Down+Enter to accept. This blocked automated polecat and
agent startup.

Added AcceptBypassPermissionsWarning() to tmux package that:
- Checks if the warning dialog is present by capturing pane content
- Only sends Down+Enter if "Bypass Permissions mode" text is found
- Avoids interfering with sessions that don't show the warning

Updated all Claude startup locations:
- session/manager.go (polecat sessions)
- cmd/up.go (mayor, witness, crew, polecat cold starts)
- daemon/daemon.go (crashed polecat restarts)
- daemon/lifecycle.go (role session starts)
