config.yaml: new repo-root config file with docs_folders list
(docs, documentation, doc). apply.sh reads this list and picks the
first existing folder per project instead of hardcoding docs/.
Instructions:
- core-principles: add No Vibe Coding and No Touching .ai/ sections
- ai-root-instructions: add mandatory instructions block — rules stay
active for the whole session, not just at start; AI must stop and
announce if instructions were not loaded
- project-context, docs: updated to list all docs folder alternatives
and reference config.yaml as the source of truth
FR-5.0 added to apply-requirements.md. README step 4 updated.
