fix(ci): Make perf-report job safer and more robust

- Add input validation for tag format
- Check for required tools (curl, jq, bc)
- Skip if report already exists (idempotent)
- Add colored logging for better visibility
- Handle push failures gracefully
- Use 'rules' instead of 'only' for modern GitLab CI
- Add GIT_DEPTH: 0 for full history access
