Zod v4 changed z.record(valueType) to z.record(keyType, valueType).
The single-arg form now sets keyType, leaving valueType as undefined.
This caused tools/list to throw 'Cannot read properties of undefined
(reading _zod)' when the SDK tried to serialize the metadata field to
JSON Schema, silently returning an error for every tools/list call and
making all MCP tools invisible in claude.ai.

available trips, create/update/delete journey and entries, reorder,
contributors CRUD, preferences, share link management)
- Add Journey resources (trek://journeys and sub-resources)
