Fix Claude -- Init

Create a new CLAUDE.md from the production-grade template that reverses Claude Code's built-in limitations discovered in the source code leak.

Workflow

Step 1: Verify No Existing CLAUDE.md

Check that CLAUDE.md does not already exist:

if [ -f "CLAUDE.md" ] || [ -L "CLAUDE.md" ]; then
  echo "ERROR: CLAUDE.md already exists. Use fixclaude:update instead."
  exit 1
fi

If it exists, tell the user to use fixclaude:update instead and stop.
