test(agent-skills): stub resolveStateDir in core mock

[lalalune]

What

Follow-up to #13270: the newly merged skill-discovery-helpers.test.ts imports code paths that reach packages/skills, which now expects @elizaos/core.resolveStateDir. The plugin-agent-skills Vitest setup hand-mocks @elizaos/core, so the focused test failed during import with:

No "resolveStateDir" export is defined on the "@elizaos/core" mock

This adds a deterministic resolveStateDir stub to the package test mock.
