Upgrade Remix to 3.0.0 beta 4

[kentcdodds]

Summary

• Upgrade remix from 3.0.0-beta.0 to 3.0.0-beta.4.
• Migrate server route/action imports to the beta.1+ remix/router and remix/routes subpaths.
• Replace removed BuildAction annotations with public Action<typeof routes...> contracts.
• Adapt Remix UI components to read render props from handle.props.
• Update the custom D1 data-table adapter for plain-SQL migration scripts via executeScript(sql) and remove the old schema-builder migration compiler.

Walkthrough

Notes

• Reviewed beta.1 through beta.4 release notes plus fetch-router@0.20.0, ui@0.3.0, data-table@0.3.0, test@0.5.0, and assert@0.3.0 package notes.
• router.mount() was considered but not applied because this app currently has one flat route contract used by both server and client code; adding mounted groups would not reduce complexity in this shape.

Testing

• bunx prettier --check package.json server/router.ts server/routes.ts server/handlers/account.ts server/handlers/auth-handler.test.ts server/handlers/auth.ts server/handlers/chat-threads.ts server/handlers/chat.ts server/handlers/health-handler.test.ts server/handlers/health.ts server/handlers/home.ts server/handlers/login.ts server/handlers/logout.ts server/handlers/password-reset.ts server/handlers/session-handler.test.ts server/handlers/session.ts server/handlers/signup.ts client/editable-text.tsx worker/d1-data-table-adapter.ts
