tinyjuice 0.2.1

# Unified Diffs

Real TinyJuice and OpenHuman patches. The diff compressor keeps file headers, hunk headers, and changed lines while collapsing long unchanged context.

Each row links to the full raw input and the exact compacted output used by the benchmark.

Inline previews are fenced as `diff`, so GitHub highlights additions and removals directly in the report.

## What TinyJuice Is Doing

Diff compression preserves review-critical structure: file headers, hunk headers, additions, and removals. Long unchanged context is collapsed because it is recoverable and usually lower value.
