[BUG] updateMessageMetadata fails on custom postgres schema due to hardcoded public.role_type_enum

[simple10]

Describe the bug

Role Type enum fails when using postgres custom schema when updating message metadata..

It appears the "public" schema is hard coded in at least one place:
https://github.com/getzep/zep/blob/main/src/store/schema_common.go#L79

To Reproduce

1. Create a custom postgres schema for zep
2. Set schema_name to the custom schema in zep.yaml
3. Attempt to update zep message metadata

Expected behavior

Allow for enums in custom schemas and not just public schema.

Logs

Here's the example code I'm running...

https://github.com/LLemonStack/llemonstack/blob/main/examples/zep/zep.ts#L131

Fails on await client.memory.updateMessageMetadata

All other requests seem to work in the example script. It's only updateMessageMetadata that throws an error.

The role_type_enum was created by zep in the custom schema: zep_schema.role_type_enum

Environment (please complete the following information):

• Zep version: 1.0.2 CE (I think) from zepai/zep:latest docker pulled today
• Zep SDK and version: zep-js 2.0.2
• Deployment: local Docker

Additional context
Add any other context about the problem here.

A quick workaround is to just create an alias in posgres for public.role_type_enum to map to the custom schema:

CREATE DOMAIN public.role_type_enum AS custom_zep_schema.role_type_enum;

Where custom_zep_schema is whatever custom schema was created for zep to use.
