Subject: [PATCH 2/2] refactor: improve generic reconciliation, secret caching,
 yaml merging, and test coverage

- Enhance staged reconciliation pipeline in src/apply/ to support parallelization and better resource enrichment logic
- Implement caching in HashiCorp Vault secret resolver to prevent redundant HTTP requests
- Optimize profile-specific YAML deep-merging logic
- Add comprehensive unit/integration tests in tests/coverage_improvement_test.rs to boost code coverage
- Update project documentation (README, AGENTS.md, GEMINI.md, testing.md) to reflect new features and architectural changes

 Secret handling is managed via the `SecretResolver` trait, which allows for multiple resolution strategies:

 - **CompositeResolver**: Chains multiple resolvers in a prioritized order.
 
 The masking heuristic during `inspect` looks for keys matching these patterns:
