fixes nonSnakeCase bug

[techiejd]

Fixes case where the knowledge pool collection does not follow snake_case convention.

---

Note

Ensures embeddings tables are resolved/updated using snake_case mappings so knowledge pool names that aren’t snake_case work correctly.

• Use toSnakeCase when resolving tables in afterSchemaInitHook and when issuing raw SQL updates in vectorize task (src/index.ts, src/tasks/vectorize.ts)
• Add integration tests covering non-snake-case pool names and initialization (dev/specs/vectorSearch.spec.ts)
• Bump version to 0.4.4 and update CHANGELOG.md; add to-snake-case dependency
