feat: bundle more dependencies

[chenjiahan]

• Bundle more dependencies
• Enable dts bundle (https://rslib.rs/config/lib/dts#dtsbundle)

[Copilot]

Pull request overview

This PR updates the build/package setup so more runtime libraries are bundled into the published server build, and TypeScript declarations are generated as a bundled/rolled-up .d.ts output.

Changes:

• Add an explicit chunk name for the dynamic chokidar import to stabilize bundling output.
• Switch the server dts configuration to a bundled declarations mode and configure ws env defines to avoid optional native deps.
• Move previously runtime-declared deps (chokidar, connect-next, ws, @types/ws) out of dependencies (now installed for build via devDependencies) and update the lockfile accordingly.
