Zero v28

Zero release 28, built from commit 94db842.

Changes

Fixed

• zcashd: the mainnet end-of-service halt moves from block 3,471,448
  (~2026-09-04) to 3,527,448 (~2026-10-23), with the shutdown warning from
  block 3,511,320 (~2026-10-08). Every release from v20 through v27 embedded
  the v20 release height, so all of them halt at 3,471,448; there is no
  runtime override, only a new binary moves it. Testnet and regtest are not
  affected. (#59)
• zebra: the mainnet end-of-support halt moves from block 3,545,960
  (~2026-11-08) to 3,564,960 (~2026-11-24), the horizon of upstream zebra
  6.3.0, with the warning from block 3,548,832 (~2026-11-10). v26 and v27
  both reported 3,545,960 because neither re-vendored zebra. Zero now carries
  the release height and re-sets it at every release. (#59)
