feat(webdav): add complete file system support

  - Add nc_webdav_list_directory tool for browsing any NextCloud directory
  - Add nc_webdav_read_file tool with automatic text/binary content handling
  - Add nc_webdav_write_file tool supporting text and base64 binary content
  - Add nc_webdav_create_directory tool for creating directories
  - Add nc_webdav_delete_resource tool for deleting files and directories
  - Extend WebDAV client beyond Notes attachments to general file operations
  - Add XML parsing for WebDAV PROPFIND responses with metadata extraction
  - Improve type annotations throughout codebase for better IDE support
  - Add comprehensive documentation with usage examples

  This transforms the NextCloud MCP server from a limited Notes/Tables tool
  into a full-featured file system interface, enabling complete NextCloud
  file management through LLM interactions.

+### WebDAV File System Access
+
+The server provides complete file system access to your NextCloud instance, enabling you to:
+
+- Browse any directory structure
+- Read and write files of any type
+- Create and delete directories
+- Manage your NextCloud files directly through LLM interactions
+
+**Usage Examples:**
+
+```python
+# List files in root directory
+await nc_webdav_list_directory("")
+
+# Browse a specific folder
+await nc_webdav_list_directory("Documents/Projects")
+
+# Read a text file
+content = await nc_webdav_read_file("Documents/readme.txt")
+
+# Create a new directory
+await nc_webdav_create_directory("NewProject/docs")
+
+# Write content to a file
+await nc_webdav_write_file("NewProject/docs/notes.md", "# My Notes\n\nContent here...")
+
+# Delete a file or directory
+await nc_webdav_delete_resource("old_file.txt")
+```
+
