remix test

This release consolidates changes from multiple beta versions into a single supported prerelease (Beta.10), introducing a new `remix db` workflow, full-stack HMR, and significant API changes for improved structure and functionality.

Introduced `remix.json` for CLI configuration and new `remix db` commands for database management. Enhanced `remix test` argument parsing and added HMR support.

This pre-release introduces major breaking changes focused on modularizing exports, updating context derivation patterns using `MiddlewareContext`, and standardizing controller file locations to `app/actions`. It also integrates Remix's internal `node-tsx` loader for testing and execution.
