Bump @sourceacademy/conductor to 0.8.0

[martin-henz]

Summary

• Bumps @sourceacademy/conductor from ^0.5.0 to ^0.8.0.
• 0.8.0 includes conductor#53: hostLoadPlugin/requestLoadPlugin become async (Promise<void> instead of void), and the RPC procedure is renamed from the notification $requestLoadPlugin to the awaitable requestLoadPlugin.

Why no code changes

The only call site, src/runner/module-loader/src/index.ts's loadTab callback (this.__conductor.hostLoadPlugin(tabName)), is fire-and-forget and its return value is already discarded, so it compiles and behaves the same against the new Promise<void> return. eslint on that file is clean (no floating-promise rule configured in this repo).

Test plan

• yarn eslint src/runner/module-loader/src/index.ts passes
• yarn build / yarn test — currently broken on this machine's Node 20 (fs.glob requires Node 22+) independent of this change; verified via git stash that the same failures reproduce on unmodified main. Should be re-run in CI (Node 22+) before merge.

Draft — not merging yet.
