feat(www): arbitrary trend date ranges with presets and All time - #194
Replace the Last 30/60/90/120 days picker with a Vercel-style range picker: presets Today, 1 week, 1 month (default), 1 year and All time, plus a range calendar limited to published dates. Legacy range=30|60|90|120 URLs still work.
No trend-window cap; the axis stays calendar-spaced up to 1,100 days. The API, openapi, llms.txt, MCP and markdown follow the same window rule.
The scenario trend reads each run's summary, and summaries now also carry the date's package/process counts and versions (falling back to the files for old summaries). Cold All time: 2,917 -> 424 requests. Needs a data republish.
Chart islands take columnar series and trend columns (lossless), cutting the All-time page from 6.52 to 4.61 MB. Trend marks stay visible in forced colors.
The production data URL in .env.example and comments is benchmarks-data.vlt.io (benchmarks.vlt.sh now serves the site's HTML); the site origin fallback is benchmarks.vlt.io.
Summary by CodeRabbit
New Features
Trend reports now offer calendar-based presets from today through the full archive, plus custom date ranges spanning any published dates.
Charts support longer timelines and clearer markers for DNF results, version changes, and unusual runs.
Published summaries can include package counts, process counts, and version information.
Improvements
Reports use summary data when available and continue to support older archives.
Updated the site and data service addresses.
Documentation
Documented summary data and clarified trend-range options.

Walkthrough
The changes add optional counts and version metadata to date summaries, introduce named and uncapped custom trend windows, and update report loading and chart data to use those changes. Production data and site hostname references also change.
Changes: Report data and trends
Layer / File(s)
Summary
Summary metadata and published format apps/data/src/summary.ts, apps/data/src/index.ts, apps/data/test/summary.test.ts, docs/METHODOLOGY.md
Date summaries now include optional package counts, process counts, and versions under reserved keys. Accessors, exports, tests, and documentation cover these fields and their availability.
Preset and custom trend windows apps/www/src/lib/params.ts, apps/www/src/components/range-picker.tsx, apps/www/src/app/openapi.json/route.ts, apps/www/src/app/llms.txt/route.ts, apps/www/src/lib/api.ts, apps/www/src/lib/markdown.ts, apps/www/src/lib/mcp.ts, apps/www/src/app/[section]/[[...params]]/page.tsx, apps/www/test/scenarios.test.ts
Named presets become the default range, while legacy numeric ranges remain accepted. Custom ranges can span any length when their dates are published and ordered. The picker supports draft calendar ranges and displays live run counts.
Report loading obtains summaries for trend dates and uses them when available. Missing optional summary data falls back to fetching source files. Tests compare summary-backed trends and leaderboards with file-backed results.
Dense chart series and rendering apps/www/src/lib/chart-model.ts, apps/www/src/components/charts-echarts.tsx, apps/www/src/components/fixture-trend.tsx, apps/www/src/components/pinned-run.tsx, apps/www/src/app/globals.css, apps/www/src/lib/api.ts, apps/www/src/lib/markdown.ts, apps/www/src/lib/opengraph/templates.tsx, apps/www/test/honesty-inventory.test.ts, apps/www/test/report.test.ts, apps/www/test/app-cwd.ts, apps/www/vitest.config.mts
Chart data and trend details use column-oriented series, with conversions to rows where report output or chart rendering needs them. The dense calendar limit increases to 1,100 days. Chart marks use CSS masks, and tests cover conversion behavior and sparse values.

The OpenAPI range enum omits the legacy values that the API still accepts.
apps/www/src/app/openapi.json/route.ts lists only the preset values in the range enum. The parameter description and loadReportParams both accept 30, 60, 90, and 120. Clients that validate against /openapi.json or generate types from it can reject those legacy values before they send the request.

Update the OpenAPI range parameter schema so its enum includes the preset values
and the legacy day-count values accepted by loadReportParams, converting legacy
values to strings to match the parameter’s string type. Keep the existing
default and description unchanged.
