hooks-registry-drifts-silently-as-hooks-are-added

hooks-registry.md does not auto-update when new Python hooks or Hookify rules are added to the filesystem — after several sessions of hook development, only 23% of Python hooks and 44% of Hookify rules were documented. This creates a dangerous gap where future sessions cannot discover or audit the full hook surface. Registry must be updated as part of the same commit that adds any new hook, treated as a mandatory cascade target.
