Subject: [PATCH] fix(installer): copy hooks lib modules during update

Copy templates/hooks/lib into ~/.claude/hooks/lib for standalone installs and update reconciliation so .mjs hooks keep resolving stdin and atomic-write helpers after omc update.

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode)
