Plain links, no Ko-fi script, so the site CSP and the extension's permissions are unchanged. The extension change needs a store upload with the Sunday release. Also updates docs/SITE-PLAN.md for the portfolio repo rename (s-portfolio is now ajithakdev.com). CHANGELOG and RESOURCES-AND-GUIDE updated.

Lint: 0 errors (6 warnings, unchanged). Tests and docs checks pass.

Pre-merge checklist

Addressed

• "Support on Ko-fi" link in the site footer (every page through _partials/footer.html)
• One line with a Ko-fi link on the extension's options page
• No Ko-fi script; the site CSP and the extension's permissions are unchanged

Tested

• npm run build passes; the link is in dist/index.html, about/ and 404.html
• npm test passes, docs checks PASS (19)
• npm run lint: 0 errors; the 6 warnings come from JS files this PR doesn't touch
• Options page opened in a loaded extension

CI and release

• check passes
• Sunday release: tag, wrangler deploy, store uploads (the extension change needs the upload)

Docs

• CHANGELOG line under Unreleased
• RESOURCES-AND-GUIDE.md Ko-fi row; SITE-PLAN.md renamed for ajithakdev.com

After merge: goes out with Sunday's release.
