deepshrink-core 0.2.1

DeepShrink core: pure, testable logic (size parsing, presets, engine contract).
Documentation

deepshrink-core — the pure, testable core of DeepShrink.

No I/O side effects: size/preset parsing, file-type detection and the engine contract (Engine). The heavy lifting (invoking ffmpeg) happens in a concrete engine's run layer; here we keep the math and types, unit-tested.
