* fix(pi): complete locally handled prompts
Slash commands the Pi CLI handles without starting a model turn previously
left the Paseo turn hanging until interrupt. Parse the optional
agentInvoked correlation from prompt acknowledgements, surface
command_output/notify output as timeline content, and complete the turn
locally when no agent turn will start. Older Pi binaries without the
correlation are detected via a getState compatibility probe.
* review: guard command output without an active turn, simplify delegates
- Drop late-arriving command_output when no turn is active instead of
emitting an orphaned timeline item with turnId undefined
- Remove redundant 'text' in event check (type is already narrowed)
- Inline recordNoTurnNotification delegate
* refactor(pi): consolidate local prompt state
