Refactor CLI Config Manager and Add Provider Model Routes

- Removed deprecated constants and functions from cli-config-manager.ts.
- Introduced new provider model presets in litellm-provider-models.ts for better organization and management of model information.
- Created provider-routes.ts to handle API endpoints for retrieving provider information and models.
- Added integration tests for provider routes to ensure correct functionality and response structure.
- Implemented unit tests for settings persistence functions, covering various scenarios and edge cases.
- Enhanced error handling and validation in the new routes and settings functions.

 **Why Path-Based**: Agent (code-developer.md) autonomously:
-- Reads and parses task JSON (requirements, acceptance, flow_control)
-- Loads tech stack guidelines based on detected language
-- Executes pre_analysis steps and implementation_approach
+- Reads and parses task JSON (requirements, acceptance, flow_control, execution_config)
+- Executes pre_analysis steps (Phase 1: context gathering)
+- Checks execution_config.method (Phase 2: determine mode)
+- CLI mode: Builds handoff prompt and executes via ccw cli with resume strategy
+- Agent mode: Directly implements using modification_points and logic_flow
 - Generates structured summary with integration points
 
 Embedding task content in prompt creates duplication and conflicts with agent's parsing logic.
