What's New
v6.4.1 adds native execution and diagnostic skills; v1.21.0 adds font weight metadata and PDF header fixes.
Breaking Changes

New Features
- Native (inline) execution mode for 'executing-plans'.
- `diagnosing-superpowers` skill identifies session issues.
- `font_weight` metadata (100-900) added to text items.
- Opt-in `bold_from_weight` API for text items.
- Support for OpenCode 2.0, Muse, and Qwen Code.
Improvements
- Subagent-driven development isolates workspaces to prevent plan collisions.
- Fixes off-canvas labels leaking into surrounding text.
- Tolerates leading bytes before the `%PDF-` header.
- Writing plans includes a 'Review Focus' section.
