Subject: [PATCH] Add multi-stage Dockerfile (17MB binary, SQLite volume,
 healthcheck)

rust:1.99-slim build, debian-slim runtime as uid 10001. Only static/
and content/ shipped alongside the binary; DB lives on /data volume.
Could not build-verify locally (no Docker daemon); paths checked
against ServeDir/include_str usage instead.
