/**
 * Tests for v6.3.0 Level 3 — native tool registration.
 *
 * codex adapter:
 *  1.  write() injects ## Tools JSON block into AGENTS.md
 *  2.  block contains exactly 5 sigmap tool entries
 *  3.  all 5 expected tool names are present
 *  4.  each tool has name, description, and command fields
 *  5.  idempotent — second write does not duplicate the block
 *  6.  human content above the tools block is preserved
 *  7.  ## Tools block appears before ## Auto-generated signatures
 *
 * claude adapter:
 *  8.  write() injects ## Bash allowlist into CLAUDE.md
 *  9.  block contains sigmap Bash permission patterns
 * 10.  idempotent — second write does not duplicate the block
 * 11.  human content is preserved
 * 12.  ## Bash allowlist appears before ## Auto-generated signatures
 * 13.  block includes node gen-context.js* pattern
 *
 * bundled factories (gen-context.js):
 * 14.  bundled codex write() injects ## Tools block
 * 15.  bundled claude write() injects ## Bash allowlist
