agent: cut generic e-commerce bullets from Mercado Libre adapter

Adapter notes ride along with every first-turn request on the site, so
they should carry only what the model cannot infer. Drops the variant-
selection and price-excludes-shipping/installments bullets, which are
generic marketplace advice, and folds the postal-code rule into one
line. Keeps the site-specific content: locale-exact buy labels, the
catalog vs single-seller URL split, the Mercado Pago hand-off, and the
account-verification stop.

Notes go 2041 -> 1217 chars (5 bullets), from 5th-largest adapter to
19th of 74.
