v2.0.0

2.0.0 (2025-12-06)

Features

• rename runners to harnesses and implement new unified frontmatter keys (66ad305)

BREAKING CHANGES

• The 'runners' directory is now 'harnesses'. Old names still work via aliases.

New unified frontmatter keys with backward-compatible deprecated aliases:

• approval: enum ("ask" | "sandbox" | "yolo") replaces allow-all-tools
• tools: nested { allow, deny } replaces allow-tool/deny-tool
• dirs: replaces add-dir
• session: unified { resume, fork } replaces resume/continue
• output: replaces output-format

All harnesses (Claude, Codex, Gemini, Copilot) updated with:

• New key handling with ?? fallback to deprecated keys
• Consistent approval mode mapping across backends
• Session resume support via unified object
• Output format standardization

Tests updated with 95 passing tests covering both new and deprecated keys.
