feat: kubedog integration with unified resource handling (#2383)

* feat: add kubedog-based resource tracking integration

Add kubedog tracking as an alternative to Helm's --wait flag with:
- Real-time deployment progress tracking
- Container log streaming
- Fine-grained resource filtering (trackKinds/skipKinds/trackResources)

Features:
- New pkg/resource package for unified manifest parsing and filtering
- New pkg/kubedog package wrapping kubedog library
- CLI flags: --track-mode, --track-timeout, --track-logs
- Helmfile YAML support for trackMode, trackTimeout, trackLogs, trackKinds, skipKinds, trackResources
- Case-insensitive kind matching for filtering
- Multi-context support with proper kubeconfig/kubeContext handling

Tracking supports: Deployment, StatefulSet, DaemonSet, Job

Resource filtering priority (highest to lowest):
1. trackResources - explicit resource whitelist
2. skipKinds - blacklist specific kinds
3. trackKinds - whitelist specific kinds

Integration:
- Disable Helm --wait when using kubedog tracking
- Track after successful Helm sync/apply
- Respect release.Namespace as fallback for resources without namespace
- Use getKubeContext() for correct cluster targeting

Tests:
- Unit tests for resource filtering and kubedog options
- Integration test with httpbin chart
- E2E snapshot tests for YAML serialization
- Documentation in docs/advanced-features.md

* fix: address PR #2383 review comments (round 4)

1. resource/filter.go: Skip empty whitelist entries in matchWhitelist
   - At least one field (kind/name/namespace) must be specified
   - Prevents matching all resources with empty TrackResources entries

2. config/apply.go: Add ValidateConfig for track-mode validation
   - Validate --track-mode must be 'helm' or 'kubedog'
   - Reject invalid values like --track-mode foo

3. config/sync.go: Add ValidateConfig for track-mode validation
   - Same validation as apply command
   - Ensures consistent behavior across commands
