🧪 Add unit tests for dep-versions utility

[sunnylqm]

🎯 What: The testing gap in src/utils/dep-versions.ts was addressed. The module computes and exports versions for local project dependencies by reading package.json.
📊 Coverage: Added test coverage for scenarios involving missing package.json, no dependencies, fully resolvable dependencies sorted properly, gracefully skipped missing packages, and deduplication between dependencies and devDependencies.
✨ Result: Solid test coverage ensures modifications to dep-versions are safely tested in completely isolated temp directories, ensuring both require and filesystem behavior is reliable.

📝 Walkthrough

Walkthrough

A new Bun test suite is added for the depVersions utility. Each test runs in an isolated temporary directory with a chdir-based setup/teardown and uses a cache-busting dynamic import to force re-evaluation of the utility. Five test cases cover absent package.json, missing dependency fields, version resolution with alphabetical sorting, skipping unresolvable packages, and deduplication across dependencies and devDependencies.

Changes

depVersions test suite

Layer / File(s)	Summary
Test infrastructure: imports, setup/teardown, and cache-busting loader tests/dep-versions.test.ts	Imports Bun test utilities and Node.js fs/path modules, establishes per-test temp directory lifecycle (mkdtemp, chdir, restore, rm), and defines loadDepVersions to dynamically import the utility with a unique query string to bypass the module cache.
Behavioral test cases tests/dep-versions.test.ts	Five tests verify: returns {} when package.json is absent; returns {} when neither dependencies nor devDependencies exist; resolves versions from node_modules with alphabetically sorted keys; silently skips unresolvable packages; deduplicates a package listed in both dependency fields.

Poem

🐇 Hop through the temp dirs, one by one,
Cache-busting modules just for fun!
Empty package.json? No sweat, no fuss—
Sorted keys and dedup, leave nothing to discuss.
The rabbit checks deps with a satisfied thud. 🌿

🚥 Pre-merge checks | ✅ 4 | ❌ 1

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The PR title uses an emoji and vague phrasing ('unit tests') that lacks specific detail about what is being tested, making it less informative for scanning history.	Consider a more descriptive title without emoji, such as 'Add unit tests for dep-versions utility' or 'Test depVersions module behavior across scenarios'.
