Subject: [PATCH] fix(gecko): replace dead WBNB/BUSD pool with active USDT/WBNB
 v3 (#920)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Symptom: alertmanager fires 'geckoterminal head_lag stale on bnb'
every few hours across all 3 regions in both staging and prod
(observed 2026-07-06). Root cause: the BNB pool configured across
3 harnesses uses PoolID '24' which points to WBNB/BUSD
PancakeSwap V2 — near-idle since Binance stopped issuing BUSD in
2024. Staging-sgp logs show 2 gecko/bnb samples per 5000 log lines
vs 7 for base and 1 for solana; the sub-5min sample cadence the
head_lag rule expects is impossible on a dead pool.

Fix: replace with PancakeSwap V3 USDT/WBNB 0.01% fee tier,
currently the #1 BSC pool by volume ($130M+ 24h). Internal GT
pool_id = 160787671 (derived from
app.geckoterminal.com/api/p1/bsc/pools/0x172fcd41e0913e95784454622d1c3724f546f849).

Applied to all 3 harnesses that hardcode the same list:
- aggregator-head-lag   (fires the alert)
- aggregator-latency-benchmark
- metadata-coverage
