PR Summary

Low Risk
Low risk instrumentation-only change: adds a new PostHog event emitted when users stop generation in mothership or copilot, without altering server logic or data flows.

Overview
Adds a new PostHog analytics event, task_generation_aborted, to track when users click Stop generation.

Home (mothership) and workflow Panel (copilot chat) now wrap stopGeneration with a handler that captures the event (including workspace_id and view) before aborting generation, and apps/sim/lib/posthog/events.ts is updated to type the new event and properties.

Greptile Summary

This PR adds PostHog analytics tracking for when users abort AI task generation in two chat interfaces: the mothership home view and the copilot panel. It introduces a new task_generation_aborted event type (with workspace_id and view properties) and wraps the raw stop-generation callbacks in thin analytics-aware handlers that capture the event before delegating to the underlying action.

• events.ts: New task_generation_aborted event added to PostHogEventMap with workspace_id and a discriminated view union ('mothership' | 'copilot')
• home.tsx: stopGeneration replaced with handleStopGeneration in both chat components; reuses the existing posthogRef pattern already present in the file
• panel.tsx: New posthogRef + sync useEffect added (matching the pattern from home.tsx); copilotStopGeneration replaced with handleCopilotStopGeneration for the panel chat component

Confidence Score: 5/5

Safe to merge — minimal, well-scoped analytics addition with no logic changes

The PR only adds PostHog event tracking with no changes to core logic. The implementation correctly reuses the existing posthogRef pattern, uses optional chaining in captureEvent (no risk of throwing), and is typed end-to-end via PostHogEventMap. No issues found.
