test(graph): add types massive-scaling performance tests

[pari-dubey1]

Description

Fixes #4395

Deploys a robust, entirely deterministic, high-volume stress testing suite located at lib/graph/types.massive-scaling.test.ts. Because lib/graph/types.ts is a pure declaration asset containing only TypeScript interfaces, this suite validates type-checking integrity, structure conformity, and large-scale indexing access parameters under extreme limits without relying on flaky execution clocks or random variables.

Summary of Test Case Coverages:

1. 1,000 GraphNodes Allocation: Confirms that a massive network array structure instantiates and maps safely when strictly bounded by the GraphNode schema properties.
2. 10,000 GraphEdges Scaling: Targets deep structural nested loops by populating 10,000 sequential GraphEdge elements inside a single hub node container without memory leaks or index boundary slips.
3. 5,000 RecommendedTechnology Profiles: Evaluates compilation stability and property assignment mechanics across large dataset listings conforming to the structural RecommendedTechnology contract.
4. Oversized String Array Blocks: Loads the reasons[] array field with 2,500 distinct, heavy byte-character text trace parameters to ensure elements do not face structural truncation or mutation.
5. High-Index Lookup Terminals: Executes extreme boundary access validation by querying a collection scaled to 25,000 records, cleanly matching keys directly at the absolute terminal indexing slots.

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement
• 🕐 Pillar 3 — Timezone Logic Optimization
• 🛠️ Other (Automated performance type scaling expansion and code optimization verification)

Checklist before requesting a review:

• I have read the CONTRIBUTING.md file.
• I have tested these changes locally (npx vitest run types.massive-scaling).
• 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., test(graph): ...).
• I have updated README.md if I added a new theme or URL parameter.
• I have starred 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.
