Feature: Add file or directory movement function

This PR implements the file and directory move functionality as requested in #108.

Changes

• Added /-/move API endpoint (POST method).
• Implemented hMove handler in httpstaticserver.go to handle move operations.
• Refactored getRealPath to use a helper resolvePath method for consistent path resolution.
• Added comprehensive permissions and existence checks.
• Implemented overwrite logic for existing destinations.
• Added comprehensive unit tests in move_test.go covering:
  • Moving files and directories.
  • Moving to new (non-existent) parent directories.
  • Handling conflicts (destination already exists).
  • Handling non-existent source.
  • Permission checks.

API Usage

Endpoint: POST /-/move

Parameters:

• src: Source path (relative to root)
• dst: Destination path (relative to root)
• overwrite: Set to true to overwrite destination if it exists (optional, default: false)

Responses:

• 200 OK: Success {"success": true}
• 400 Bad Request: Missing src or dst
• 403 Forbidden: Insufficient permissions
• 404 Not Found: Source does not exist
• 409 Conflict: Destination already exists
• 500 Internal Server Error: File system error

Verification

The feature was verified with a local integration test suite covering file/directory movement, overwrite logic, and permission checks.
