## Summary
- Add Python script to sanitize GitHub issue markdown (removes HTML
comments, zero-width characters, excessive whitespace, details/summary
tags)
- Add unit tests with 5 golden input/output pairs plus additional inline
tests
- Update fix-issue.md to use sanitizer and proceed directly with
implementation for straightforward plans (no remote session question)
- Add goldens directory to format ignore to preserve test data

## Test plan
- Run `python3
.claude/commands/dyad/scripts/test_sanitize_issue_markdown.py` to verify
all 13 unit tests pass
- Test the sanitizer directly: `echo "<!-- comment -->" | python3
.claude/commands/dyad/scripts/sanitize_issue_markdown.py`

## Summary by cubic
Adds a Python markdown sanitizer and integrates it into the fix-issue
flow to clean GitHub issue content and enable direct local
implementation for straightforward plans.

- **New Features**
- Added sanitizer script that removes HTML comments, invisible
characters, excessive blank lines, and strips details/summary tags while
keeping content; normalizes line endings and whitespace.
- Updated fix-issue.md to run the sanitizer and let simple plans proceed
directly to local implementation without the remote session prompt.
- Included golden files and unit tests (13) to validate sanitizer
behavior.
- Added the goldens directory to formatter and Prettier ignore lists to
preserve test fixtures.

- **Bug Fixes**
- Fixed shell injection risk in fix-issue.md by using printf in the
sanitizer step.

<sup>Written for commit 226f9436ba6f338efd6fb798aa327334459647aa.
