Improve CLAUDE.md based on review feedback

- Specify Python 3.8+ as minimum version in project overview
- Document INI_Parse.py, dbconn.py, and davcmd.py in architecture
- Clarify run() vs runserver() functions in server.py
- Add pip install command for optional MySQL dependency
- Note that tests should be run from repository root

 ## Project Overview
 
-PyWebDAV3 is a Python 3 implementation of a WebDAV server and library supporting WebDAV levels 1 and 2 (including LOCK/UNLOCK). The project provides both a standalone server (`davserver`) and a library for integrating WebDAV capabilities into applications.

 ## Architecture
 
@@ -15,11 +15,14 @@ The codebase is organized into two main packages:
 - **AuthServer.py**: Provides HTTP Basic Authentication layer on top of standard HTTP server.
 - **iface.py**: Abstract interface class (`dav_interface`) that defines the contract for backend data sources. Any custom backend must implement this interface to handle property retrieval, data access, and resource management.
 - **propfind.py, report.py, davcopy.py, davmove.py, delete.py**: Separate classes for each DAV method that handle XML parsing and response generation.
+- **davcmd.py**: Utility functions for DAV operations (copyone, copytree, moveone, movetree, delone, deltree).
 - **locks.py**: `LockManager` class implementing WebDAV level 2 locking functionality.
+- **INI_Parse.py**: Configuration file parser for server settings.
+- **dbconn.py**: Database connection utilities for optional MySQL support.
 - **utils.py, status.py, errors.py, constants.py**: Utility functions and definitions.
 
 ### pywebdav/server/ - Reference Server Implementation
-- **server.py**: Entry point for the standalone server. Includes `runserver()` function and command-line parsing. Installed as `davserver` console script.
+- **server.py**: Entry point for the standalone server. Contains `run()` function (CLI wrapper with argument parsing) and `runserver()` function (internal server startup). The `davserver` console script calls `run()`.
 - **fshandler.py**: `FilesystemHandler` class implements the `dav_interface` for serving files from a local filesystem. This serves as the reference implementation for custom backends.
 - **fileauth.py**: `DAVAuthHandler` - authentication handler implementation.
 - **mysqlauth.py**: `MySQLAuthHandler` - optional MySQL-based authentication.
