This release introduces Model Context Protocol (MCP) support for API
development, new policies for query parameter manipulation and API metering,
enhanced CLI commands, and improvements to console logging in the runtime.

### New Features 🎉

- **Query Parameter to Header Inbound Policy** - New policy that allows
  transforming query parameters into HTTP headers, enabling more flexible
  request handling and backend compatibility.

- **Model Context Protocol (MCP) Support** - Added comprehensive MCP server
  handler for local editing experience with improved schema validation, URL
  pattern support, parameter descriptions and examples. MCP enables AI-powered
  tools to interact with your APIs more effectively.

- **Console Logging Support in Runtime (preview)** - Developers can now use
  console logging directly in the runtime environment, making debugging and
  monitoring easier during development.

- **OpenMeter Metering Inbound Policy** - New integration with OpenMeter for API
  usage metering, enabling precise tracking and billing of API consumption.

- **Enhanced Prompt Injection Policy** - Added "strict" mode with more granular
  logging capabilities to better protect APIs from prompt injection attacks in
  AI-powered applications.

- **Improved CLI Commands**:
  - New `zuplo source` command replaces the deprecated `zuplo project` command
  - Added interactive selection for account, project, and environment values in
    authenticated commands
  - Environment variables from public vars are now written to `.env` files for
    better local development experience
