v0.2.0:30 — Two copy fixes: pubkey tip + Licenses search

- "Embed your public key" tip now says "your product's source code"
  instead of "your app's source" — clearer for operators distributing
  libraries, services, or anything that isn't an app.
- Licenses search row: dropped Nostr npub from the placeholder, the
  description text, and the search-field dropdown. The purchase flow
  doesn't capture buyer npubs yet, so the option had nothing to
  find. Backend search-by-npub path is untouched — re-expose the UI
  option once buyer npub capture lands in the purchase flow.

UI copy only.

   '**How.** Each `.tier` card is now a CSS subgrid that shares row tracks with the parent `.tiers` grid. Eight named rows: launch-meta → name → original-price → price → meta-block → description → features (1fr) → button. Each section in the card emits with an explicit `grid-row`, so omitted sections (e.g. Creator has no struck-through original-price line) just leave the row empty while still preserving the alignment across siblings. The features row is `1fr` so it absorbs vertical slack, pinning the Select button to the bottom of every card.',
