Commit Message

SCAL-310982 Fix Analytics Engine single-index writes (#141)

## Summary

Fix the Workers Analytics Engine payload so production writes succeed again.

Cloudflare only accepts a single index per data point. The current sink writes
five indexes, which causes every Analytics Engine write to fail in production.

## What Changed

- switch the Analytics Engine sink to a compact AE-specific row layout with one
  tenant-scoped index and a bounded blob set
- keep is_done, drop is_thinking, and add analytical_session_id as
  Analytics-Engine-only context for session debugging
- propagate analyticalSessionId through the metrics context and attach it to the
  session creation and send-session-message tool flows
- update sink, recorder, request, MCP server, and ThoughtSpot service tests to
  lock the new schema

## Notes

- keep mcp_metrics_v2; production writes were failing, so this becomes the
  first valid persisted layout rather than a new version bump
- local design docs were updated for reference only and are not part of this
  repo commit
