PRs #63 and #65 were each green pre-merge but changed and consumed
the same arr-core surface; merging both broke main. Size bands are
now gibibytes with a points penalty, evaluate takes size_bytes, and
Policy carries score_weights (column wiring tracked in #68).

Eleven empty crates per DESIGN.md §11, versions and lints pinned once in the
root manifest, Justfile carrying the §12 gate, nix dev shell.
The frontend steps in `just ci` no-op until web/ exists. arr-core carries one
placeholder test because `cargo nextest` fails a zero-test run, and relaxing
that would let a broken filter go green later.
Closes#1
