Git and churn enrichment microcrate for tokmd analysis presets.
Documentation
# tokmd-analysis-git

Git-history enrichments for tokmd analysis presets.

## Problem

You need churn, freshness, and coupling signals from git history without
mixing them into the core scan or format layers.

## What it gives you

- `build_git_report`
- `build_predictive_churn_report`

## Integration notes

- Consumes git-derived inputs and produces analysis-side enrichment reports.
- Keeps history-based heuristics separate from the receipt model and renderer.
- Deterministic ordering is preserved through the shared analysis types.
