fix(examples): use top-level await for async functions

Replace unawaited function calls with top-level await to fix oxlint
no-floating-promises errors. This ensures examples run to completion
and any errors are properly surfaced.

- examples/index.ts: await quickstart()
- examples/openai-integration.ts: await openaiIntegration()
- examples/ai-sdk-integration.ts: await aiSdkIntegration()
- examples/human-in-the-loop.ts: await humanInTheLoopExample()
- examples/meta-tools.ts: await main() in import.meta.main guard
