Maintenance: Code Quality Review - 2026-06-03

[dbeley]

Code Quality Improvements

Changes Made

• Type hints: Added Optional[] type hints for parameters with None defaults (album, track, date, timestamp)
• Simplified timestamp generation: Replaced complex time.mktime(datetime.datetime.now().timetuple()) with simpler int(time.time())
• Removed unused import: Removed datetime import that was no longer needed

Rationale

These changes improve type safety, code readability, and remove unnecessary complexity while maintaining the same functionality.

Manual Review Needed

• Verify that the simplified timestamp generation produces the expected behavior in all scenarios
