✅ Technical code review

- Excellent structure: The entire system is encapsulated with good separation of responsibilities.

- The log is synchronized with [UdonSynced] and is updated only by the Master, avoiding conflicts.

- ScrollRect support: Automatically detects the ScrollRect to maintain scrolling at the end of the log.

- Extended functionality: Includes _CopyLog() to duplicate log content in plain text, ideal for administrators or exporting.

- Clean and organized RichText: Ideal for quick reading and with a clear aesthetic.

- Ownership security: Ensures the Master is the owner before modifying the log, preventing errors.

- Support for other time zones (not just hardcoded UTC-5).
