Benchmarks Website v3

Rewrites the benchmarks website. Replaces the static `data.json.gz` model
with a single Rust server binary that owns a DuckDB database and accepts
`POST /api/ingest` from CI.

Design:
- Single binary: axum + maud (SSR HTML) + DuckDB + Chart.js. All static
  assets `include_bytes!`'d.
- 5 fact tables (compression time, query measurement, vector search, RAG,
  random access). Backup is a file copy.
- Ingest: versioned JSON envelopes, bearer-token gated.
- Migrator ports v2 history forward via a classifier that routes each
  record to a fact table or skips it with a typed reason.
- Charts/groups slug-addressed, URL round-trip with no DB lookup.
- Routes: `/`, `/chart/{slug}`, `/group/{slug}`, `GET /api/chart/{slug}`.
- Deploy: one binary, one DuckDB file, one `INGEST_BEARER_TOKEN`.
