[RobotHanzo]

Investigated the test-server CI failure here.

Root cause: this bumps @nestjs/core alone from 11.2.1 → 12.0.1, but @nestjs/common (and the rest of the @nestjs/* family — platform-*, websockets, testing, etc.) stay on the 11.x line. NestJS 12's @nestjs/core/metadata-scanner.js imports @nestjs/common/internal, which only exists as @nestjs/common/internal.js starting in the 12.x line — v11's @nestjs/common doesn't export that subpath at all, so every e2e spec fails at import time with Cannot find module '@nestjs/common/internal'.

This isn't fixable by patching this repo's code — the whole @nestjs/* family needs to move to 12.x together (and a NestJS major bump can carry its own breaking changes worth reviewing on top of that, e.g. decorator/DI behavior). Standing down on merging this PR alone rather than landing a guaranteed-broken server.

Recommend either scoping a dedicated bump that upgrades the full @nestjs/* family to 12.x at once and re-validates the server test suite, or adding a Dependabot group for the @nestjs/* packages (.github/dependabot.yml) so future bumps move them in lockstep instead of one at a time.
