v0.1.0 - Initial MVP

Initial alpha release of agents-md-debugger.

Highlights:

• scan, explain, and doctor commands
• text and JSON output
• Codex config support for byte limits, fallback filenames, and project root markers
• metadata-only global instruction reporting
• composite GitHub Action
• tested on Python 3.11, 3.12, and 3.13

This independent community tool models the public Codex documentation. It does not inspect Codex internals or guarantee that a model will follow an instruction.
