v3.14.0 — 按预测染色 + 重置后 →NN% 过低修复

Changed

• Rate-limit windows (5h/7d) now color by where usage is HEADED, not where it
  is right now. Once a →NN% end-of-window projection exists, the window's
  bar fill, label, and ⏰ clock take a severity from the projected value
  against the cap: green below 80%, yellow 80–99%, red at 100%. The bar's fill
  LENGTH and printed % still track current usage — only the color is projected.
  So a 7d window sitting at 24% but on track for →96% now reads yellow instead
  of a falsely-healthy green. Applies to all three styles (classic bar, capsule
  ● dot, hairline mini-bar). Before a projection exists, the window falls back
  to current-usage coloring on the configured thresholds (unchanged).

Fixed

• The →NN% projection no longer reads far too low for the first ~15 minutes
  after a window resets. The smoother was seeded from the used=0 first
  post-reset tick (where the raw projection collapses to the bucket prior ~2%),
  then crawled up with an 8-minute time-constant — so a 5h window 6 minutes in
  at 1% used showed →14% when the pace already implied ~50%+. The projection
  now holds the →-- placeholder until MIN_ELAPSED (5h=10m, 7d=1h) — the same
  floor the ⚡ETA chip already uses — and then seeds from the first trustworthy
  reading (no lag). During the hold the window colors by current usage, an
  honest "not enough signal yet" instead of a fake-precise low number.
