Export default CSR subject fields from core-cli device-id-cmd

[jchris]

Problem

The deviceIdRegisterEvento handler in @fireproof/core-cli accepts a ReqDeviceIdRegister with subject fields (country, organization, locality, state), but the default values for these fields are only defined inline in the cmd-ts option definitions in cmds/device-id-cmd.js:

country: option({ defaultValue: () => "WD" }),
organization: option({ defaultValue: () => "You did not set the Organization" }),
locality: option({ defaultValue: () => "You did not set the City" }),
state: option({ defaultValue: () => "You did not set the State" }),

When calling deviceIdRegisterEvento.handle() directly (instead of shelling out to core-cli deviceId register), callers must duplicate these defaults. The server rejects empty strings — e.g. country must be >= 2 chars.

Request

Export a defaultCsrSubject constant (or similar) from @fireproof/core-cli so direct callers can use it:

export const defaultCsrSubject = {
  country: "WD",
  organization: "You did not set the Organization",
  locality: "You did not set the City",
  state: "You did not set the State",
};

Context

vibes.diy CLI switched from shelling out to core-cli deviceId register to calling deviceIdRegisterEvento.handle() directly (VibesDIY/vibes.diy#1313). Had to hardcode the defaults to avoid CSR validation errors.
