fix(pulumi): drop exports map so Pulumi can serialize the provider (v0.0.2)

Pulumi's closure serializer reaches the dynamic provider's internal submodules
(dist/engine.js, dist/kinds.js) by subpath. An `exports` allowlist with only
"." blocks that: `pulumi preview` failed with "package.json export path for
.../dist/kinds.js not found". Removing `exports` (keeping main/types) lets the
serializer resolve them. Verified end-to-end: a real `pulumi up` from
kubernetes-deployment updated mcpd's qwen3-thinking llm and it probes 200.
