Audit and adopt Remix v3 Beta 5 features

[kentcdodds]

Summary

• document a repository-specific Remix v3 Beta 5 adoption audit
• adopt remix/ui/button, remix/ui/input, and remix/ui/checkbox in repeated authentication forms
• generate auth/password-reset mutation URLs from the typed route contract
• minify production web and MCP app browser bundles
• make the MCP bundle test assert stable protocol behavior instead of minified implementation names

Scope decisions

• trustProxy is not applicable because production runs as a Cloudflare Worker, not through remix/node-fetch-server
• Node production-start and Frame resolver defaults are documented but intentionally not copied into the Workers/custom-router architecture
• session/CSRF middleware and chat Listbox work are proposals because they require security or interaction design decisions

Validation

• bun run typecheck
• bun run lint
• changed-file Prettier check
• bun run build
• bun run test:e2e e2e/login.spec.ts e2e/oauth-authorize.spec.ts — 7 passed
• bun run test:mcp — 4 passed
• bun run test:e2e e2e/calculator-widget.spec.ts — 3 passed
• manual login, checkbox, and reset-password visual checks with no console errors

Production browser output decreased from 432,978 bytes to 190,168 bytes (56% smaller). The repository-wide Prettier check still reports unrelated pre-existing formatting issues outside this diff; all changed files pass.
