ADR-0011 action item 1: the AVIF decoder moves to sqzer-rav1d on every target, and wasm32 gets AVIF decoding with it.

What and why

re_rav1d was archived in June and never built for wasm32. sqzer-rav1d is upstream rav1d main at d3d1cd6, which has the safe Rust API of upstream PR 1439 that no release carries, plus one commit: on wasm32 the crate aliases itself as libc and a 17-line file provides the names it uses there. Every other target keeps the real libc. The library is still named rav1d.

In sqzer-codecs the decoder moves out of the non-wasm dependency table, the cfg gates go, and decode.rs changes its import, the error variant name and a Vec to a Box<[u8]>.

# the wasm32 build in Node 24, before: "unrecognised image format"
pattern-rgb.avif -f auto:  Avif 48x32 via ravif target=Quality(48.0) search=6 trials, score 72.1, reached true
pattern-10bit.avif -f png: Png 48x32 via png target=Lossless
pattern-rgba.avif -f png:  Png 48x32 via png target=Lossless
pattern-rgb.jpg -f auto:   Avif 48x32 via ravif target=Quality(40.0) search=6 trials, score 72.8, reached true

So a wasm32 build reads AVIF, takes a perceptual target for AVIF output and defaults to AVIF for photos. --list-codecs and --json name the decoder rav1d.

The first push ran CI against the fork through a temporary git patch, before the crate was published: all six targets, native and portable, and wasm32 passed. The second commit drops the patch for sqzer-rav1d 0.1.0 from crates.io.

ADR-0011 item 1 is annotated, not ticked. The fix is offered upstream as memorysafety/rav1d#1505. Two parts are left: the AVIF fixtures in the wasm test, which arrives with item 3, and retiring the fork once an upstream release has the Rust API and that fix.

New dependencies

sqzer-rav1d 0.1.0, BSD-2-Clause, in place of re_rav1d 0.1.3. strum moves from 0.26 to 0.27 with it. paste is still pulled, so the advisory ignore stays.

Checklist

• CHANGELOG.md has an entry under ## Unreleased
• no new ADR
• tests cover the change; golden scores are unchanged: 375 portable and 348 native tests pass locally with no score moved
• cargo fmt, cargo clippy --all-features, cargo test, cargo doc and cargo deny check pass locally

Summary

The PR replaces re_rav1d with sqzer-rav1d and enables AVIF decoding on wasm32. The change since the previous review updates the ADR action item to record the opened upstream pull request and the remaining work.
