feat: add pnpm run link:dev for local development

- scripts/link-dev.sh: one-command setup to switch ~/.uncaged-nerve
  to use monorepo packages instead of npm registry versions
- Builds all packages, links CLI globally, links all @uncaged/*
  packages into the nerve workspace, and restarts daemon
- Prevents version mismatch between CLI and daemon during development
