Captures per-LLM-call token usage tagged by feature (copilot chat,
track block, meeting note, knowledge sync), plus sign-in / sign-out
and identity. Renderer and main share one PostHog identity so events
from either process resolve to the same user.
See apps/x/ANALYTICS.md for the event catalog, person properties,
use-case taxonomy, and how to add new events.
