fix: resolve CI test failures and fix 429 retry bug in authentik client

- Fix isTransientError() logic bug: 429 (Too Many Requests) was caught by
  4xx range check before reaching the 429-specific retry check, meaning
  rate-limited requests were never retried (RFC 6585 violation)
- Add CGO dependencies (librados-dev, librbd-dev, libcephfs-dev, libvirt-dev)
  to all CI workflow jobs to fix compilation failures
- Fix ai_test.go: correct timeout assertion (30s Anthropic default, not 60s),
  use bitmask permission checks instead of exact mode comparison, disable
  retries in timeout test to prevent flaky timing
- Fix config_test.go: use bitmask check for directory permissions (0750 vs 0700)
- Fix environment_test.go: .env files don't match config extension patterns,
  use config.yaml for analyzer test
- Fix unified_client_test.go: mock transport now respects context cancellation,
  rewrite retry-after tests to avoid 120s blocking, use t.Fatal for nil guard
- Remove flaky retry summary CI step (redundant with proper test fixes)
- Add explicit test timeouts in CI (10m unit, 5m backup)
