octoturge bd4ad00159 Fix worker Docker build: pin builder to bookworm to match runtime glibc
rust:1.97 (unsuffixed) now resolves to a trixie base, whose newer glibc
produced a binary the bookworm-slim runtime stage couldn't load
("GLIBC_2.38 not found (required by mcmapper-worker)"), crash-looping the
container on every start. Pinning the builder to rust:1.97-bookworm matches
the runtime's Debian release. Confirmed by rebuilding and running the real
image — worker now starts and runs (its next failure is an unrelated,
expected MinIO connectivity gap, not this).

# Pinned to -bookworm to match the bookworm-slim runtime stage below — the plain `rust:1.97` tag
# now resolves to a trixie base, whose newer glibc produced binaries the runtime's older glibc
# couldn't load ("GLIBC_2.38 not found"), confirmed by actually running the built image.
