fix: resolve autodiscovery tests and cursor bot image matching issues

1. Fix cursor bot image matching bug in isKotsadmImage:
   - Replace flawed prefix matching with proper image component detection
   - Handle private registries correctly (registry.company.com/kotsadm/kotsadm:v1.0.0)
   - Prevent false positives with proper delimiter checking
   - Add helper functions: containsImageComponent, splitImagePath, removeTagAndDigest

2. Fix autodiscovery test failures:
   - Add TestMode flag to DiscoveryOptions to control KOTS diagnostic collection
   - Tests use TestMode=true to get only foundational collectors (no KOTS diagnostics)
   - Preserves production behavior while enabling clean testing

Resolves failing TestDiscoverer_DiscoverFoundational tests and cursor bot issues
