fix: Always apply pagination to context_get to prevent token limit errors

- Modified context_get handler to always use the enhanced query path
- Ensures consistent pagination with default limit of 100 items
- Prevents MCP token limit errors when querying large channels
- Removes the unpaginated simple query path that was causing issues

This fixes the issue where context_get would return all items in a channel
without pagination, causing responses to exceed the 25000 token limit.
