The Rust crate release job failed in Cargo 1.96.0 while waiting for registry confirmation. For example, both independent derive crates were uploaded, but only one was confirmed available; Cargo reported a false deadlock instead of continuing to wait before publishing their dependents.

Upgrade the pinned Rust toolchain from 1.96.0 to 1.99.1, which includes the upstream fix in rust-lang/cargo#17071. The workflow continues to use cargo publish --workspace.

Validation:

• cargo fmt --all -- --check
• RUSTFLAGS='-D warnings' cargo test --all-features --locked — 188 tests passed.
• cargo publish --workspace --dry-run --allow-dirty --locked — all 6 publishable crates verified; no uploads performed.
