contree v3.0.0

Breaking changes

• Replaced the former monolithic workflow skill with focused setup skills and the explicit change-without-me full-arc workflow.
• Refined the test-tree contract around consumer-driven EARS behavior, one tree per test file, and the distinct Journey, System, Component, Adapter, Use-case, Domain, and Port seams.
• Setup now installs and proves project-local feedback loops instead of treating setup as one generic scaffolding operation.

New capabilities

• Added focused skills for test feedback, conventional linting, architecture linting and repair, mental-model steering, test-tree steering and bootstrap, and mutation testing.
• Added change-without-me to carry an idea through change, sync, outside-in TDD, mutation feedback, completion sync, and independent second opinion without routine phase transitions.
• Added stronger mental-model discovery, existing-project behavior discovery, test-tree coverage metadata, and architecture-boundary guidance.
• Expanded Claude Code and Codex compatibility, deterministic journey harnesses, independent review, and visual change explanation.
• Strengthened SessionStart and Stop steering, skill discoverability, frontmatter validation, documentation, and the Contree website.
