mars_getEntry
Fetch a MARS registry entry by DID.

Feature and dispatch boundary
This method exists in the shared method catalog. Its handler is outside the primary dispatch mapping or unavailable in this source profile. Treat catalog membership separately from current endpoint support; an unknown-method or feature-gate error is a failure, not a successful empty result.
Responses and failures
Check HTTP status, parse the JSON-RPC envelope, reject error, and require result on success. Preserve large base-unit integers without floating-point rounding. A catalog method does not bypass authentication, capability, policy or activation requirements.
