fix: accept boolean and number types for manifest default field

The `default` field in `.rep.yaml` previously only accepted strings,
forcing users to quote non-string values (e.g. `default: "false"`).
This widens the JSON schema to accept string, number, and boolean,
so `default: false` and `default: 3` now validate correctly.

Backward compatible — string defaults continue to work unchanged.
