When `gt sling` targets an existing polecat session, it now waits for
Claude to be ready before sending the nudge message. This fixes issue #115
where the "Work slung" message would arrive before Claude had fully started.
Changes:
- Add getSessionFromPane() to extract session name from pane target
- Add ensureClaudeReady() to wait for Claude startup using the same
pragmatic approach as session.Start() (poll for node, accept bypass
dialog, then 8-second delay)
- Call ensureClaudeReady() before injectStartPrompt() in runSling()
The fix uses IsClaudeRunning() for a fast path when Claude is already
running, avoiding unnecessary delays for sessions that have been
running for a while.
