Free-Tier Credit Guardrails
Tightened the lifetime-use tracking that powers the free tier before upgrade prompts appear.
This release tightened lifetimeuse tracking so gated features stop cleanly once the free allowance is spent. The free tier now feels more deliberate, and the upgrade prompt appears at a more sensible point in the flow.
Fixed counter sync after refresh.
Improved upgrade prompt timing.
Handled signout and signin more cleanly.
