v0.2.0:35 — Free tiers render as "Free" on the buy-page tier card

Previously the server rendered a 0-priced tier as "0 sats" (or
"0.00 USD") in the tier-card headline. The price card below the
tier picker already swapped to "FREE" via the JS path, so the
two surfaces disagreed.

Now: when post-discount price is 0, the tier card renders the
headline as "Free" with no unit suffix and no cadence-suffix
("Free /yr" would be incoherent). recurring_meta ("Renews
annually") still surfaces beneath for recurring-free edge cases,
so cadence isn't lost — just not stuffed into the headline.

Cosmetic; no API or schema change.
