heatmap and SVG

services/heatmap_window.py slices dailyContributions to all, last_365, or year. Comment in the file: it mirrors CodeTrace/src/api/unifiedClient.ts::windowUnifiedHeatmap.

Aliases accepted: 365, last365, last365days, days, last_year. Passing year with view=all becomes view=year. Unknown view, or view=year without year, is HTTP 400.

Windowed fields (totalSubmissions, streaks, dailyContributions, startDate, endDate) describe the slice. yearlyContributions and availableYears always describe full history so a year picker still has every year.

Canonical build_heatmap windows with ("all", None) then the route windows again from query params. The legacy heatmap dict on the same response has a smaller local _window_heatmap that does not recompute currentStreak. Read data if you care about streaks.
