Separate JavaScript and Rust package roots

[konard]

Summary

Fixes #160.

• split JavaScript package metadata, release scripts, docs, lockfiles, and Changesets state into js/
• added Rust-specific README, changelog, release scripts, and rust.yml CI/release workflow under rust/
• replaced the combined release workflow with separate js.yml and rust.yml workflows using js-v and rust-v release tag prefixes
• documented and tested that the former root scripts/ directory was fully removed, with JS scripts under js/scripts/ and Rust scripts under rust/scripts/
• added docs/case-studies/issue-160/ with issue/PR data, template snapshots, verification logs, and implementation notes
• fixed Windows Rust test portability found in PR CI (resolve_path absolute paths and streaming cwd)
• reported an upstream Rust template follow-up: Release script should remove consumed changelog fragments rust-ai-driven-development-pipeline-template#65

Testing

• bun test js/tests/repository-layout.test.mjs
• cd js && bun run lint
• cd js && bun run format:check
• ./js/node_modules/.bin/prettier --config js/.prettierrc --check docs/case-studies/issue-160/README.md js/tests/repository-layout.test.mjs
• cd js && bun run check:duplication
• cd js && PATH=/tmp/issue-160-bin:$PATH bun run test (684 pass, 5 skip)
• cd rust && cargo fmt --all -- --check
• cd rust && cargo clippy --all-targets --all-features
• cd rust && cargo test --all-features --verbose
• cd rust && cargo test --doc --all-features --verbose
• cd rust && cargo package --allow-dirty
• rust-script --test rust/scripts/publish-crate.rs
• rust-script --test rust/scripts/version-and-commit.rs
• Ruby YAML parse for .github/workflows/js.yml and .github/workflows/rust.yml
• PR CI on 82c1a5a: JavaScript checks and release passed; Rust checks and release passed

Notes

Local sudo was unavailable, so the full JavaScript suite used a temporary downloaded jq binary, matching the CI job's jq dependency setup.

Working session summary

Done. PR 161 is updated and ready:

#161

Current head is e8ac08d on issue-160-a2a2313cf693, working tree is clean, and PR is not draft.

Both latest CI runs passed on that head:

• JavaScript checks and release: success
• Rust checks and release: success

Implemented the JS/Rust package-root split, separate workflows/releases/docs/scripts, the issue-160 case study, and Windows-safe Rust test fixes found during CI. I also filed the Rust template follow-up here:

link-foundation/rust-ai-driven-development-pipeline-template#65

Did we process all the scripts at root ./scripts folder as per requirements?

Yes. I audited the former root ./scripts contents and pushed follow-up commit 82c1a5a to make that explicit.

Current disposition:

• former JavaScript release scripts were moved to js/scripts/
• scripts/publish-to-crates.mjs was replaced by rust/scripts/publish-crate.rs
• scripts/sync-rust-version.mjs was removed because JavaScript and Rust now release independently through their own version-and-commit scripts
• the repository root no longer has a scripts/ directory

I also added regression coverage in js/tests/repository-layout.test.mjs and documented this in docs/case-studies/issue-160/README.md.

Follow-up is complete and PR 161 is ready for review again.

• Pushed 82c1a5a with explicit coverage that root scripts/ no longer exists and release scripts live under js/scripts/ or rust/scripts/.
• Updated the issue-160 case study with the disposition of the former root scripts.
• Updated the PR description and replied to the root-script audit question: Separate JavaScript and Rust package roots #161 (comment)
• Latest CI on 82c1a5a passed for both workflows:
  • JavaScript checks and release: https://github.com/link-foundation/command-stream/actions/runs/27143918613
  • Rust checks and release: https://github.com/link-foundation/command-stream/actions/runs/27143918556
