Add automated local link and asset checker

[GsCommand]

Motivation

• Provide a repeatable, repo-local audit to catch broken internal HTML links and missing static assets before releases.
• Keep checks lightweight and dependency-free by using a small Node script with only built-in fs/path modules.

Description

• Add scripts/check-local-links.mjs which scans public/**/*.html, extracts local refs from href, src, content (when starting with /), and url(...) inside inline <style> blocks, and resolves them against public/ using static resolution rules.
• Add check:links npm script in package.json to run the checker via node scripts/check-local-links.mjs.
• The checker ignores external schemes (http(s)://, mailto:, tel:, javascript:), hash-only links, and allowlisted dynamic routes /api/verify, /api/examples/coinbase-webhook, /api/examples/x402-paid-action, and /verify/r.
• The script fails with a non-zero exit code if any referenced local target is missing or if any file in the repository contains the forbidden icon2.png token.

Testing

• Ran npm test which passed all automated tests (95 passed, 0 failed).
• Ran npm run check:links iteratively during development, fixed self-reference and allowlist issues, and the final npm run check:links invocation succeeded with the message All local links/assets resolved across 24 HTML files..
• Verified there are no occurrences of the forbidden token with grep -RIn "icon2.png" . 2>/dev/null which returned no matches (exit code indicates none found).
