chore: require a fee receiver at build time, ignore internal docs

The build now fails fast when KYBERSWAP_FEE_RECEIVER is unset instead of
shipping a bundle that sweeps output fees nowhere. Documents the key in
.env.example alongside what it actually costs: 0 bps on direct swaps, 9 bps
on ZAP's embedded swap leg.

Docs are written for the private tree and get copied in by mistake during a
sync, so *.md is ignored by default and publishing one is opt-in.
