fix: escape control characters in filenames

[sxyazi]

Fixes #3321

[Copilot]

Pull request overview

This PR fixes control character escaping in filenames by introducing a new printable character conversion system and improving path handling. The changes replace manual string manipulation with a more robust API and fix several edge cases in path cleaning logic.

• Introduces replace_to_printable and push_printable_char functions to handle control character escaping with Unicode replacement characters
• Fixes path cleaning logic to properly track URI/URN counts when removing parent directory references
• Adds trailing separator normalization to prevent inconsistencies in path handling
