概要

CI の Rust のツールを，flake の devShell から動かす形にする．手元と CI で同じ版になり，flake.lock で中身が固定される．

変更

項目	内容
devShell	aarch64-darwin に加えて x86_64-linux でも使えるようにした（genAttrs）．ツールは元から揃っていた
ci.yml	lint，format，test，audit から setup-rust-toolchain，cargo-deny-action，cargo-machete を削除
各 job	checkout → nix-setup（v1.3.0，SHA 固定）→ run．defaults.run.shell は nix develop --command bash -eo pipefail {0}（job ごと．all-green は nix なしで動かすため）
不変	job 名（必須チェック）と all-green の needs

CI の時間

	全体の待ち時間
変更前（main 直近 5 回）	36〜74 秒（38，74，73，52，36）
変更後（この PR の run）	ツールの job は最長 56 秒（audit）．lint 38，format 45，test 48 秒

main の run には review がないので，比べるのはツールの job の時間．ツールの job は並列で，最長の audit（56 秒）が全体の待ち時間を決める．これは変更前の 36〜74 秒の範囲に収まっている．ただし，変更前の job ごとの時間は取っていないので，job 単位の前後比較はしていない．

検証

• nix flake check --all-systems --no-build --option allow-import-from-derivation false が通る
• Linux の devShell は cache から取得できる（126 パス，約 280 MiB，ソースビルドなし）
• devShell 内で cargo clippy，cargo fmt --check，cargo test，cargo machete，cargo deny check bans licenses sources が成功

Review summary

No findings. I didn't post any inline comments.

What I checked:

• CI jobs: lint, format, test and audit now run each step through nix develop --command bash -eo pipefail {0}, with nix-setup before them. all-green keeps the top-level bash default, and job names and needs are the same, so the required checks don't change.
• Toolchain: nixpkgs 26.05 ships a rustc new enough for edition = "2024". Removing setup-rust-toolchain doesn't change RUSTFLAGS, since it was already set to rustflags: "". clippy -D warnings is still passed explicitly.
• cargo-deny: cargo deny check runs every check, advisories included, which matches what the action did. The [advisories] section in deny.toml still applies. (The PR verification lists only bans licenses sources, so advisories will first run for real in CI.)
• flake.nix: the genAttrs refactor keeps the aarch64-darwin shell as it was and adds x86_64-linux. lefthook from unstable is still picked per system.

Blocking findings: 0
