fix: prevent LLM from suggesting full command chains in execute-command

- Updated execute-command prompt to explicitly forbid suggesting full command chains
- Added clear instruction that only the first command should be suggested for chained commands
- This ensures the LLM will only suggest the initial command and let the user decide on subsequent commands

 **Suggestion Guidelines:**
 - Suggestions use prefix matching (case-insensitive)
 - For simple commands: Include the base command (e.g., "npm", "git") and optionally a more specific pattern
-- For chained commands (using &&, ||, ;, |): Include patterns for EACH individual command in the chain
-  - Example: For "cd backend && npm install", suggest: "cd backend && npm install", "cd", "npm install", "npm"

 - Include 2-4 relevant patterns total
 - Only suggest "*" (allow all) if explicitly requested by the user
