Item 2 — founder counter is REAL or hidden (kills the hardcoded 47/100)

ClaimMeter rendered a fabricated "47 / 100 CLAIMED" (a hardcoded default; the
comment even said "Cosmetic conversion driver… Static here"). Now:

- GET /api/founders/count counts ONLY real paying founders — user_profiles
  where founder_pricing = true AND subscription_status = 'active' (the
  Stripe-webhook-synced mirror, so we never hammer the Stripe API). Cached 5
  min in Redis on top of that.
- If the source is unavailable (Supabase unconfigured, query error, column not
  migrated, client throws) the endpoint returns { available: false } and the
  ClaimMeter renders NOTHING — counter and progress bar both hidden. We never
  fall back to a number.
- A low real count is shown honestly (0 → "0 / 100"); the truth is the feature.

Next proxy at app/api/founders/count. 6 route tests cover real count, low
count, error/unconfigured/throw → hidden, and cache-hit. Suite 271/3260 green,
web build exit 0.

+ * GET /api/founders/count — the REAL founder-seat counter.
+ *
+ * TRUTH LAW (Truth-Everywhere Part 2, item 2): the ClaimMeter used to render a
+ * hardcoded "47 / 100 CLAIMED". This counts ONLY real paying founders — the
+ * Stripe-synced subscription records in Supabase (`user_profiles` where
+ * founder_pricing = true AND subscription_status = 'active'). Counting the
+ * webhook-synced mirror, not the Stripe API, is the cache — we never hammer
+ * Stripe. Cached 5 min in Redis on top of that.
+ *
+ * If the source is unavailable (Supabase unconfigured, query error, column not
+ * migrated), we return { available: false } and the UI HIDES the counter — we
+ * never fall back to a number. A low real count is fine; the truth is the feature.
