- Add CODE_OF_CONDUCT.md based on Contributor Covenant 2.1
- Add .github/PULL_REQUEST_TEMPLATE.md with structured sections
- Link CODE_OF_CONDUCT in README.md and CONTRIBUTING.md
- Rewrite bug_report.md with professional structure and Copy Logs requirement
- Rewrite feature_request.md to focus on problem, use cases, and benefits
- CI release workflow now extracts version from tag (v1.4.0 → 1.4.0)
and injects it into manifest.base.json, shared/constants.js, and
package.json before building — the tag is the single source of truth
- Build script now copies README.md alongside constants.js and
blacklist.js from /shared → /extension/shared/ (full mirror)
- .gitignore updated: extension/shared/ is fully generated by build
- AI_INIT.md: simplified release workflow, fixed Chrome-only reference
