ci: fix npm publish auth by removing empty NODE_AUTH_TOKEN override

The OIDC provenance flow (id-token: write + setup-node registry-url)
handles auth automatically. Setting NODE_AUTH_TOKEN to an empty secret
overrides it and breaks authentication.

docs: add installation instructions and SDK example to README

- Symlink README.md into npm/pgmicro/ so npm picks it up
- Add CLI installation via npx/npm
- Add JavaScript SDK example with verified output
- Fix cli.js to chmod binary before execution (npm strips permissions)

ci: remove Turso publish/release workflows from pgmicro
