fix(rust): commit Cargo.lock in version bump to prevent cargo publish failure#254

Adding .gitkeep for PR creation (default mode). This file will be removed when the task is complete. Issue: #253
… failure When bumping the version in Cargo.toml, regenerate and commit Cargo.lock in the same commit. Without this, `cargo build --release` (run after the version commit) updates Cargo.lock, leaving it dirty. `cargo publish` then rejects publishing with exit code 101 because of uncommitted changes. Root cause: scripts/rust-version-and-commit.mjs staged Cargo.toml and CHANGELOG.md but not Cargo.lock. After the commit, `cargo build` updated Cargo.lock to reflect the new version, and `cargo publish` detected the mismatch. Fix: run `cargo generate-lockfile --manifest-path` after updating Cargo.toml and stage Cargo.lock in the same version bump commit. Also adds case study analysis in docs/case-studies/issue-253/ with CI logs, timeline, root cause analysis, and solution options. Fixes #253 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Update Cargo.lock package version from 0.8.0 to 0.9.0 to match
Cargo.toml. The mismatch caused `cargo package --list` to modify
Cargo.lock at CI time, making the working directory dirty and failing
with exit code 101 ("uncommitted changes in Cargo.lock").
- Fix Prettier formatting in changeset file: change double quotes to
single quotes in the YAML front matter to match the project's
Prettier config (singleQuote: true).

Summary
Fixes #253 — CI/CD flow for Rust publishing was failing with exit code 101 in the `Publish to crates.io` step.
Root Causes
1. Script: Missing Cargo.lock in version bump commit
The `scripts/rust-version-and-commit.mjs` script bumped the version in `Cargo.toml` and committed it, but did not include `Cargo.lock` in the commit.
The CI workflow then ran `cargo build --release`, which updated `Cargo.lock` to reflect the new version from `Cargo.toml`. When `cargo publish` ran next, it detected the uncommitted `Cargo.lock` and failed:
```
error: 1 files in the working directory contain changes that were not yet committed into git:
Cargo.lock
to proceed despite this and include the uncommitted changes, pass the --allow-dirty flag
```
Evidence: The automated `chore(rust): release v0.9.0` commit (SHA: `3c23cdb`) only contained `Cargo.toml` + `CHANGELOG.md` — no `Cargo.lock`.
2. CI Workflow: cargo package --list failing due to build-modified Cargo.lock
In the `Build Package` CI job, `cargo build --release` ran before `cargo package --list`. The build step modified `Cargo.lock`, making the working directory dirty. `cargo package --list` then failed with the same exit code 101 / "uncommitted changes" error.
Fixes
Fix 1: `scripts/rust-version-and-commit.mjs`
Fix 2: `.github/workflows/rust.yml`
Move `cargo package --list` before `cargo build --release` in the `Build Package` job. This way the working directory is clean when the package check runs.
Fix 3: `js/.changeset/fix-rust-cargo-lock-version-bump.md`
Add required changeset file to pass the JS CI/CD "Check for Changesets" check, which requires exactly one changeset per PR when `scripts/` files are modified.
