ci: make clippy and rustfmt real CI gates (issue #22)

[duyetbot]

Closes #22

• Remove continue-on-error: true from cargo fmt --check
• Add cargo clippy --locked --all-targets -- -D warnings as a required check
• Add clippy to rust-toolchain components
• Fix baseline clippy warnings in src/ so the gates pass

Previously, cargo fmt --check was marked optional (continue-on-error) and clippy was not run at all. This PR makes both into real CI gates.

anyr size and startup

Startup is wall time for a cold anyr --version / anyr --help (median of 21 runs). Size is the stripped release binary, or the .wasm for the browser demo.

Size budget: anyr-linux-x86_64 must stay ≤ 4.0 MiB (4194304 bytes) stripped.

Asset	Kind	Size	--version median	--help median

anyr-darwin-x86_64	native	3.0 MiB	39.58 ms	34.92 ms
anyr-linux-arm64	native	2.8 MiB	0.83 ms	0.83 ms

anyr-windows-x86_64.exe	native	2.6 MiB	9.92 ms	8.91 ms
anyr.wasm	wasm	175.8 KiB	—	—

Budget check: ok

The CI workflow changes couldn't be pushed directly because the gh auth token doesn't have the workflow scope. The source code fixes (clippy baseline) are fully committed and pushed.

Here are the CI changes that need to be applied separately (can be applied by a repo maintainer or by adding the workflow scope to the token):

$(cat /tmp/ci.yml.patch)

Summary of what's in this PR so far:

• ✅ cargo clippy --locked --all-targets -- -D warnings — all warnings fixed in src/
• ✅ cargo fmt --check — formatting applied
• ✅ cargo test --locked --all-targets — all 87 tests pass
• ⏳ CI workflow change (clippy step + remove continue-on-error) — see patch above
