Extract formatToolLine to shared output module

[jancurn]

Summary

Refactored the formatToolLine function to be a shared utility in the output module instead of being duplicated in the grep command module.

Key Changes

• Moved formatToolLine function from src/cli/commands/grep.ts to src/cli/output.ts and exported it as a public function
• Updated formatToolsSummary in src/cli/output.ts to use the new formatToolLine function, eliminating inline formatting logic
• Updated imports in src/cli/commands/grep.ts to import formatToolLine from the output module instead of defining it locally
• Removed duplicate function definition from grep.ts

Implementation Details

• The function maintains the same formatting behavior: displays tool name with parameters, annotations, and task execution mode in a compact bullet-point style
• Both modules now use the same centralized implementation, reducing code duplication and ensuring consistent formatting across the CLI
