Readability: Duplicated ResampleQuality type definition across modules

[m96-chan]

Summary

The ResampleQuality type alias is defined in multiple places, violating the DRY principle.

Locations

1. src/proctap/core.py:27
2. src/proctap/backends/init.py:18
3. src/proctap/backends/converter.py:20

Problem

Each module defines its own copy:

ResampleQuality = Literal['best', 'medium', 'fast']

This means:

• Changes must be made in 3 places
• Risk of inconsistent updates
• Harder to maintain

Suggested Fix

Define ResampleQuality in a single location (e.g., backends/base.py or a dedicated types.py) and import from there.
