Replace legacy scripts with separated ots/node hooks
- Remove deprecated scripts/ directory (6 files) - Add hooks/post-commit-ots (ots CLI version) - Add hooks/pre-commit-ots (ots CLI backfill) - Add hooks/post-commit-node (Node.js version, local proofs only) - Add hooks/pre-commit-node (Node.js backfill, no upgrade) - Update hooks/install.sh to auto-detect and install matching hooks - Update documentation (SKILL.md, README.md, AGENTS.md) - Add node_modules/ to .gitignore for Node.js mode Breaking change: Scripts removed, use new hooks/ directory.
