* chore(ci): add path filters to skip CI for docs-only changes
- test.yml: Only run on changes to backend/**, frontend/**, or the workflow itself
- docker-build.yml: Only run on code/docker changes (tags still trigger unconditionally)
* docs: move screenshots below GIF and add visual indentation
- Bug report template with deployment type, browser info, logs
- Feature request template with affected area, priority
- Config with link to discussions and README
- Optimize test.yml to skip tests for non-code changes
