ci(greptile): add review config with application-sdk cross-reference

Add .greptile/ configuration to enable Greptile code reviews with
cross-repository awareness of atlanhq/application-sdk as a pattern
repository. Includes rules for SDK API alignment, version pinning
checks, and test coverage for SDK integration points.

+## SDK Compatibility
+
+This repository depends on `atlanhq/application-sdk`. When reviewing changes, consider:
+
+- **SDK API usage**: pyatlan uses SDK base classes and services. Any change to how
+  these are called or extended must match the SDK's current API surface.
+- **Version compatibility**: When the SDK dependency version changes, verify that
+  pyatlan's usage is compatible with the new version's interfaces.
+- **Behavioral assumptions**: Changes that rely on specific SDK behavior (e.g.,
+  ObjectStore path normalization, Dapr service defaults, Temporal workflow semantics)
+  should be validated against the SDK's documented or tested behavior.
+
+## Key Integration Points
+
+- `pyatlan.client` — SDK client wrappers and API interactions
+- `pyatlan.model` — Data models that may extend or interact with SDK types
+- `pyatlan.events` — Event handling that integrates with SDK EventStore
+- `pyatlan.cache` — Caching layer that may use SDK StateStore
