Steve Yegge e4fba408f3 feat: Add markdown-to-jsonl converter example [addresses #9]
Add lightweight example script for converting markdown planning docs
to bd JSONL format. This addresses #9 without adding complexity to
bd core.

Features:
- YAML frontmatter parsing (priority, type, assignee)
- Headings converted to issues
- Task lists extracted as sub-issues
- Dependency parsing (blocks: bd-10, etc.)
- Fully customizable by users

This demonstrates the "lightweight extension pattern" - keeping bd
core minimal while providing examples users can adapt for their needs.

"""
Convert markdown files to bd JSONL format.
This is a simple example converter that demonstrates the pattern.
Users can customize this for their specific markdown conventions.
Supported markdown patterns:
1. YAML frontmatter for metadata
2. H1/H2 headings as issue titles
3. Task lists as sub-issues
4. Inline issue references (e.g., "blocks: bd-10")
Usage:
python md2jsonl.py feature.md | bd import
python md2jsonl.py feature.md > issues.jsonl
