fix: Correct TTY check for AI progress indicator in CLI

Addresses `process.stdout.clearLine is not a function` error when running AI-dependent commands non-interactively (e.g., `update-subtask`).

Adds `process.stdout.isTTY` check before attempting to use terminal-specific output manipulations.

feat: Implement initial config manager for AI models

Adds `scripts/modules/config-manager.js` to handle reading/writing model selections from/to `.taskmasterconfig`.

Implements core functions: findProjectRoot, read/writeConfig, validateModel, get/setModel.

Defines valid model lists. Completes initial work for Subtask 61.1.

+```
+The configuration management module should be updated to:
+
+1. Separate model configuration into provider and modelId components:
+   ```javascript
+   // Example config structure
+   {
+     "models": {
+       "main": {
+         "provider": "openai",
+         "modelId": "gpt-3.5-turbo"
+       },
+       "research": {
+         "provider": "openai",
+         "modelId": "gpt-4"
+       }
+     }
+   }
+   ```
+
+2. Define provider constants:
+   ```javascript
+   const VALID_MAIN_PROVIDERS = ['openai', 'anthropic', 'local'];
+   const VALID_RESEARCH_PROVIDERS = ['openai', 'anthropic', 'cohere'];
+   const DEFAULT_MAIN_PROVIDER = 'openai';
+   const DEFAULT_RESEARCH_PROVIDER = 'openai';
+   ```
+
+3. Implement optional MODEL_MAP for validation:
+   ```javascript
+   const MODEL_MAP = {
+     'openai': ['gpt-3.5-turbo', 'gpt-4', 'gpt-4-turbo'],
+     'anthropic': ['claude-2', 'claude-instant'],
+     'cohere': ['command', 'command-light'],
+     'local': ['llama2', 'mistral']
+   };
+   ```
+
+4. Update getter functions to handle provider/modelId separation:
+   ```javascript
+   function getMainProvider() { /* return provider with fallbacks */ }
+   function getMainModelId() { /* return modelId with fallbacks */ }
+   function getResearchProvider() { /* return provider with fallbacks */ }
+   function getResearchModelId() { /* return modelId with fallbacks */ }
+   ```
+
+5. Update setter functions to validate both provider and modelId:
+   ```javascript
+   function setMainModel(provider, modelId) {
+     // Validate provider is in VALID_MAIN_PROVIDERS
+     // Optionally validate modelId is valid for provider using MODEL_MAP
+     // Update config file with new values
+   }
+   ```
+
+6. Add utility functions for provider-specific validation:
+   ```javascript
+   function isValidProviderModelCombination(provider, modelId) {
+     return MODEL_MAP[provider]?.includes(modelId) || false;
+   }
+   ```
+
+7. Extend unit tests to cover provider/modelId separation, including:
+   - Testing provider validation
+   - Testing provider-modelId combination validation
+   - Verifying getters return correct provider and modelId values
+   - Confirming setters properly validate and store both components
