PR Review: fix(rivetkit): export database provider types

Overview

This PR fixes a missing type export: AnyDatabaseProvider was defined in src/common/database/config.ts but was never re-exported through src/db/mod.ts, making it inaccessible to users importing from rivetkit/db. The fix is minimal and correct.

---

Code Quality

src/db/mod.ts — Adding AnyDatabaseProvider to the export list is the right fix. All other types from config.ts are already exported here; this was simply an omission.

tests/package-surface.test.ts — Follows the existing compile-time surface test pattern established by RestoredContextTypeSmoke. The RestoredDatabaseSurfaceTypes | null = null idiom is a pure TypeScript type check that will fail to compile if any imported type is missing or broken. This is the correct pattern for this test file.

---

Observations

• AnyDatabaseProvider = DatabaseProvider<any> | undefined — the | undefined branch represents an actor with no database configured, which makes this useful as a constraint in generic actor/framework utility types. The use of any here is intentional and appropriate for a "wildcard" type alias.
• The three types imported in the new surface test (AnyDatabaseProvider, DatabaseProvider, RawAccess) were all importable from source already — only the public package surface was broken for AnyDatabaseProvider.

---

Minor Consideration

InferDatabaseClient<T> (also in config.ts) is the natural companion to AnyDatabaseProvider — it extracts the resolved client type from a provider. Any user who stores an AnyDatabaseProvider and later needs to type the resolved client would reach for this utility type. It is currently absent from db/mod.ts. Worth considering whether it belongs in the same export list, or whether it's intentionally kept internal.

---

Summary

Clean, focused fix for a missing export. Test coverage is correctly added using the existing surface-test pattern. No correctness, performance, or security concerns.
