Track post-v0.2 analytics workspace follow-ups

[thrr87]

Non-blocking findings from the v0.2 release review:

• Keep the compact percent remaining header. Consider whether Runway and Suggested pace need a second always-visible place without adding clutter.
• Decide whether Account facts should also appear in Token activity, or update the product spec to keep them in Facts.
• Split MenuContentView by Graphs, Facts, Insights, and preflight when the next change touches those areas.
• Split CodexAssistedInsights by discovery, request, decoding, storage, and client work when the next change touches those areas.

These items do not block v0.2.0. Make each change only when the next product or maintenance task needs it.
