v0.2.0:42 — revert implicit Patron→Pro expansion from :41

The only affected license was the operator's own pre-launch
self-license under an earlier entitlement scheme. New Patron licenses
issued from the corrected master-Keysat policy carry the right
entitlements in their signed payload. The implicit expansion was
paying ongoing complexity (magic-slug behavior, hardcoded list
divergence on rename) for a one-shot migration case.

Affected operators: re-issue + Activate Keysat license. The new key
overwrites /data/keysat-license.txt and self_tier picks up live
without a restart.
