Code Review

This pull request updates the TypeScript version to 6.0.2 and modifies the tsconfig.json configuration, including updating the target to ES2023 and switching to nodenext for module resolution. Feedback was provided regarding the removal of the strict compiler option, which is recommended to be kept for better type safety.

Upgrading to TypeScript 6.0.2 may be incompatible with the currently locked build tooling: rsbuild-plugin-dts@0.20.0 (pulled in via @rslib/core@0.20.0) declares a peerDependencies.typescript of ^5, so this change will likely produce peer-dependency warnings and may break d.ts generation. Consider bumping @rslib/core (and/or rsbuild-plugin-dts) to a version that supports TS 6 (e.g. rsbuild-plugin-dts@0.20.1+ which widens the peer range).

typescript@6.0.2 is now locked, but rsbuild-plugin-dts@0.20.0 (also in this lockfile) declares peerDependencies.typescript: ^5. This unsupported peer range will typically cause install warnings and can break the d.ts build; consider updating the toolchain to a version that supports TS 6 (e.g. rsbuild-plugin-dts@0.20.1+, likely via bumping @rslib/core).
