Pull request overview

Updates the project to Platformatic/Watt 3.52.0 and integrates a Watt/Platformatic-driven shutdown path by registering a close handler via @platformatic/globals, aiming to eliminate the “missing close handler” shutdown warning while keeping Watt optional.

Changes:

• Bump Platformatic/Watt-related dependencies and the watt.json schema to 3.52.0.
• Add a Platformatic/Watt close event listener that triggers the existing shutdown flow (via a new exported close()).
• Add .npmrc to ensure package-lock.json is generated/kept.
