[Docs]: Fix broken TOC anchor and unclosed <p> tags in contributing.md

Docs

A review of contributing.md and repository configurations revealed a dead table-of-contents link, several unclosed HTML formatting tags, and missing tooling scripts:

---

1. Broken TOC Anchor in contributing.md

• Location: contributing.md line 20 vs line 133
• Details:
  The Table of Contents links to:

  - [Local Development](#local-development)

  However, the section header on line 133 is named:

  ## Working Locally

  Clicking the TOC link results in a dead anchor jump.
• Fix: Update line 20 to - [Working Locally](#working-locally) or rename the section header to ## Local Development.

---

2. Malformed / Unclosed HTML <p> Tags in contributing.md

• Location: contributing.md lines 99, 114, and 122
• Details:
  Several bullet points under the Guidelines section open with <p><strong>...</strong><br/> but lack closing </p> tags before subsequent markdown list items, causing invalid HTML structure in some markdown renderers.
• Fix: Clean up raw HTML tags and replace them with standard Markdown formatting.

---

3. Missing typecheck Script in package.json

• Location: package.json
• Details:
  TypeScript and @types/node are installed as dev dependencies, but there is no "typecheck": "tsc --noEmit" script to validate the integrity of the TypeScript scripts in scripts/. Adding this script would enable contributors and CI to verify TypeScript types on future changes.

Happy to submit a quick PR to fix these formatting and documentation issues.
