* docs: add GitHub issue and PR templates
Add structured issue templates for bug reports, feature requests, and docs reports with YAML forms. Include a pull request template with checklist for contribution quality.
* docs: add bilingual contributing guide (EN & zh-CN)
Provide detailed contribution guidelines covering development setup, coding standards, commit conventions, PR workflow, and community conduct in both English and Chinese.
Allow users to configure include/exclude glob patterns in
.open-code-review/rule.json (global or project-level) to control
which files are reviewed. Exclude has highest priority, include
penetrates default path exclusions but not the extension allowlist.
Only one layer takes effect following --rule > project > global priority.
