tokmd-analysis-complexity 1.9.0

Complexity analysis for tokmd analysis receipts.
Documentation
# tokmd-analysis-complexity

Complexity scoring and histogram generation for analysis receipts.

## Problem
You need per-file complexity and technical-debt signals without folding parsing logic into the receipt model.

## What it gives you
- `build_complexity_report`
- `generate_complexity_histogram`
- `ComplexityReport`, `FileComplexity`, `ComplexityHistogram`

## Integration notes
- No feature flags.
- Uses `AnalysisLimits` to cap bytes and file counts.
- Can attach per-function details when requested; relies on `tokmd-content` and maintainability helpers.
