test(dependencyGraph-massive-scaling): verify Massive Data Sets and Extreme High Bounds Scaling

[tamilr0727-ux]

Description

Adds large-scale performance and stress-test coverage for lib/graph/dependencyGraph.ts through the new test file lib/graph/dependencyGraph.massive-scaling.test.ts.

Changes

• Added test scenarios using thousands of mock dependency nodes and edges to simulate high-volume graph structures.
• Validated graph generation and traversal logic under extreme scaling conditions.
• Verified that coordinate calculations and graph layouts remain stable with large datasets.
• Added performance-focused assertions to ensure graph processing remains within acceptable execution thresholds.
• Tested graph integrity and output consistency when handling unusually large dependency networks.

Test Coverage

Implemented 5 test cases covering:

1. Graph construction with thousands of dependency nodes.
2. Processing of large edge collections and dense dependency relationships.
3. Stable coordinate and layout calculations under extreme scaling conditions.
4. Execution performance validation for high-volume graph datasets.
5. Integrity verification ensuring generated graph structures remain valid and complete.

Validation

• All tests pass successfully with vitest run.
• No production code changes required.
• Confirms graph generation logic remains reliable under heavy workloads.
• Provides regression protection against performance degradation and scaling-related failures.

Fixes #4393

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement
• 🕐 Pillar 3 — Timezone Logic Optimization
• 🛠️ Other (Bug fix, refactoring, docs)

Visual Preview

Checklist before requesting a review:

• I have read the CONTRIBUTING.md file.
• I have tested these changes locally (localhost:3000/api/streak?user=YOUR_USERNAME).
• I have run npm run format and npm run lint locally and resolved all errors (CI will fail otherwise).
• My commits follow the Conventional Commits format (e.g., feat(themes): ..., fix(calculate): ...).
• I have updated README.md if I added a new theme or URL parameter.
• I have started the repo.
• I have made sure that i have only one commit to merge in this PR.
• The SVG output matches the CommitPulse "premium quality" aesthetic standard (no raw elements, smooth animations, correct fonts).
• (Recommended) I joined the CommitPulse Discord community for contributor discussions, mentorship, and faster PR support.

Thanks for the PR. The test additions look solid and are well-contained within a single file. Applied labels: \level:beginner\ for single-file scope, \ ype:testing\ for test focus, and \quality:clean\ for readability.

Thanks for scaling up the dependency graph layouts! Testing for massive nested arrays and extreme boundary limits is exactly what we need to ensure the graph never overlaps or fractures under load.

Your testing logic is incredibly well structured! However, you will notice the CI pipeline is failing due to an unrelated divergence in lib/svg/themes.test.ts on the main branch.

To get a perfectly green build, simply run git pull --rebase origin main and force push. I'll be ready to approve once that runs!

Labels Applied:

• level:advanced: Edge boundary processing and layout matrices.
• type:testing: Component scaling coverage.
• quality:exceptional: Superb structural loop assertions.
• mentor:Aamod007
