Adds CLAUDE.md instructions and pre-commit hook script to verify git refs in description.yml files exist remotely before committing. This prevents Claude Code from hallucinating non-existent commit refs when creating/updating extensions, saving debugging time. Uses only built-in tools (bash, curl, grep, sed) - works on MacOS & Ubuntu without dependencies.

Intention of this PR is to add documentation for Claude Code on how to verify that the git commit refs in the
description.ymlactually exist and are not hallucinated. This should make it less error prone for anyone to add community extensions with Claude Code.For me it has struggled to do this properly and I see that many others are using Claude Code in the community so hopefully this helps a lot of people in a single one fell swoop.
