Feat: Enhance Server Manager Tools

[ChengJiale150]

see in #127

What's Changed

list_files

🚀 New Features

• Pagination Support: Added start_index and limit parameters for controling max Token return by Tool
• Pattern Filtering: Added pattern parameter supporting glob for filtering file paths
• Improved Depth Control: Changed default max_depth from 3 to 1 to prevent excessive recursion

🔧 Technical Improvements

• Code Refactoring: Moved recursive file listing logic from utils.py to list_files_tool.py for better organization
• Enhanced Error Handling: Better error handling for inaccessible directories and wrong parameter input.
• Better Description: Add use cases and range validation for the tool in the description

📝 Parameter Changes

• max_depth: Maximum depth to recurse into subdirectories (default: 1, range: 0-3)
• start_index: Starting index for pagination (default: 0, minimum: 0)
• limit: Maximum number of items to return (default: 25, 0 means no limit)
• pattern: Glob pattern to filter file paths (optional)

📋 Usage Examples

# List root directory with default settings (max_depth=1, limit=25)
list_files()

# List with custom depth and pagination
list_files(path="notebooks", max_depth=2, start_index=0, limit=50)

# Filter for Python files only
list_files(pattern="*.py")

# Deep search with no pagination limits
list_files(max_depth=3, limit=0)

assign_kernel_to_notebook

🗑️ Removed assign_kernel_to_notebook Tool:

• Completely removed the assign_kernel_to_notebook tool functionality
• Deleted assign_kernel_to_notebook_tool.py file
• Removed tool registration from tools/__init__.py
• Updated server integration in server.py
• Cleaned up related tests and documentation

Impact:

• Reduced total tool count from 16 to 15 tools
• Simplified the codebase by removing redundant kernel assignment functionality

[ChengJiale150]

Still in Progress, don't change docs.

[ChengJiale150]

This is just one of small step in #127 and I prefer to update docs and version in final PR.
