chore: structured autonomy commands for planning, generating, and implementing features

- Create sa-generate.md for generating implementation documentation from plans
- Create sa-implement.md for executing implementation plans step-by-step
- Create sa-plan.md for collaborating with users to design development plans
- Add security scan commands for CodeQL, Docker images, Go vulnerabilities, and GORM
- Implement SQL code review and optimization commands
- Add supply chain vulnerability remediation process
- Introduce backend and frontend test commands with coverage checks
- Update settings.json for command permissions
- Document governance, project overview, code quality rules, and critical architecture rules in CLAUDE.md
- Establish root cause analysis protocol and definition of done for development

+# Create GitHub Issues from Implementation Plan
+
+Create GitHub Issues for the implementation plan at: **$ARGUMENTS**
+
+## Process
+
+1. **Analyse** the plan file to identify all implementation phases
+2. **Check existing issues** using `gh issue list` to avoid duplicates
+3. **Create one issue per phase** using `gh issue create`
+4. **Use appropriate templates** from `.github/ISSUE_TEMPLATE/` (feature or general)
+
+## Requirements
+
+- One issue per implementation phase
+- Clear, structured titles and descriptions
+- Include only changes required by the plan
+- Verify against existing issues before creation
+
+## Issue Content Structure
+
+**Title**: Phase name from the implementation plan (e.g., `feat: Phase 1 - Backend API implementation`)
+
+**Description**:
+```md
+## Overview
+[Phase goal from implementation plan]
+
+## Tasks
+[Task list from the plan's phase table]
+
+## Acceptance Criteria
+[Success criteria / DoD for this phase]
+
+## Dependencies
+[Any issues that must be completed first]
+
+## Related Plan
+[Link to docs/plans/current_spec.md or specific plan file]
+```
+
+**Labels**: Use appropriate labels:
+- `feature` — new functionality
+- `chore` — tooling, CI, maintenance
+- `bug` — defect fixes
+- `security` — security-related changes
+- `documentation` — docs-only changes
+
+## Commands
+
+```bash
+# List existing issues to avoid duplicates
+gh issue list --state open
+
+# Create a new issue
+gh issue create \
+  --title "feat: Phase 1 - [Phase Name]" \
+  --body "$(cat <<'EOF'
+## Overview
+...
+EOF
+)" \
+  --label "feature"
+
+# Link issues (add parent reference in body)
+```
