v0.2.0:7 — align package copy with website positioning

The Start9 registry card was still showing "Keysat — self-hosted
Bitcoin-paid software license server" while keysat.xyz now leads
with "Bitcoin-native self-hosted licensing service for software
creators." Operators landing on the registry from the marketing
site got a jarring tagline mismatch.

Aligned everywhere the old copy was hardcoded:

- startos/manifest/i18n.ts (short + long descriptions — these
  drive the registry card)
- assets/ABOUT.md (in-StartOS About panel)
- README.md (root + licensing-service/)
- licensing-service/Cargo.toml description

Long description also picked up two updates that should have
landed when the features did but never made it into the marketing
copy:
- Zaprite mention (Bitcoin + cards) alongside BTCPay
- Recurring subscriptions + in-place tier upgrades

Pure copy change. No code, no behavior, no schema. Republishing as
:7 because the registry card text lives inside the .s9pk and
won't refresh on operators' boxes without a version bump.
