ci(release): re-enable aarch64-pc-windows-msvc target post-V0

[aram-devdocs]

Dropped from cargo-dist matrix in #265 because cargo-dist 0.28.0 has no native aarch64-pc-windows-msvc binstall artifact. binstall fell back to the x86_64 build and refused to cross-compile.

Fix options

1. Bump cargo-dist to a version that ships native aarch64 Windows artifacts (check 0.29+ release notes).
2. Switch the install step to cargo install --locked cargo-dist@VERSION instead of binstall — compiles from source on the ARM64 runner. Slower but works.

Acceptance

• Re-add aarch64-pc-windows-msvc to dist-workspace.toml targets
• Re-add the matrix entry in .github/workflows/release.yml with os: windows-11-arm
• cargo-dist build for that target succeeds against a tag
