v0.13.2

Forecast: the projected percentage is easier to read at a glance

• The projected-at-reset percentage is now bold and color-coded by risk. On
  the Session and Weekly gauge cards the forecast line kept the same wording, but
  the projected number itself is now bold and tinted green / yellow / red using
  the same thresholds as the gauge ring and favicon (gaugeColor: green below
  50%, yellow 50-80%, red 80% and up). A high projection now reads as red without
  having to parse the small print.

• The trajectory popup matches. The popup footer applies the same color-coding
  to its projected percentage, and the 80% CI moved into parentheses
  (Projected at reset: 87% (80% CI 78%-95%)) to read as a single phrase.

• The terminal point at reset is highlighted on the plot. The forecast plot
  now draws a bold, color-coded dot where the posterior-mean line lands at reset.
  That endpoint is the model's main estimate, so it now stands out from the
  trajectory fog instead of being the unmarked end of a thin line.

All three changes live in the embedded frontend (web/index.html)
and reuse the existing gaugeColor helper. No backend, pricing, or forecast-model
changes.
