# link-dev.sh — Switch ~/.uncaged-nerve to use the local monorepo packages.
#
# What it does:
#   1. Build all packages (pnpm -r build)
#   2. Link the CLI globally (nerve command → local build)
#   3. Link all @uncaged/* packages into ~/.uncaged-nerve/
#   4. Restart the daemon if it was running
#
# Usage:
#   pnpm run link:dev            # from monorepo root
#   bash scripts/link-dev.sh     # or directly
