 search_replace.py - Search and replace text in all text files within a directory (recursively)

 Usage:
   python search_replace.py <directory> <search_text> <replace_text>

 Example:
   python search_replace.py "C:\Documents\Project" "TODO" "DONE"
   python search_replace.py . "old_function" "new_function"

 Features:
   - Recursively processes all subdirectories
   - UTF-8 encoding support
   - Error handling for inaccessible files
   - Reports modified files and total count
   - Preserves file permissions and timestamps

 Requirements:
   - Python 3.6+
   - Windows/Linux/MacOS compatible
