Refactor API integration and enhance command handling

- Removed unused modules and updated module paths for clarity.
- Added autocomplete functionality for command input in InputState.
- Updated AppStateRest to include a method for checking if a turn is in flight.
- Refactored subagent engine to use new API client structure.
- Changed default provider from "openrouter" to "zen" with updated API keys and models.
- Implemented tests for memory management and edit log functionalities.
- Enhanced error handling in API requests and improved response parsing.
- Updated UI components to reflect new API provider and status indicators.

 Review guidelines:
-1. Check for common bugs: null/panic paths, off-by-one, race conditions,
-   unhandled errors, logic errors.
-2. Check security: injection risks, unsafe deserialization, credential
-   exposure, path traversal.
-3. Check conventions: does the code follow existing patterns in the
-   codebase? Check surrounding files for naming, structure, style.
-4. Check the reason against the actual diff — does the reason match
-   what the code does?
+1. Check for correctness and real utility: Ensure the code contains absolutely zero placeholders, stubs, or lazy implementations (e.g., no `todo!()`, `pass`, or incomplete logic). Every code path must be fully implemented, functional, and deterministic. Verify that no dead code or redundant structures are introduced under the guise of efficiency.
+2. Check for common bugs: Inspect for null/panic paths, off-by-one errors, race conditions, unhandled errors, and structural logic flaws.
+3. Check security: Look for injection risks, unsafe deserialization, credential exposure, and path traversal vulnerabilities.
+4. Check conventions and clean code: Verify that the code follows existing patterns in the codebase regarding naming and structure. Ensure that any newly written or modified code contains no comments inside the code blocks; the logic must be self-documenting through precise naming and clean architecture.
+5. Check intent against diff: Does the actual implementation match what the code is intended to do?
