v1.6.2

Added

• The local llama.cpp engine pin follows your macOS version. Pinned
  builds now carry their measured minimum macOS, and the host selects the
  newest compatible one: macOS 26 gets the current build, macOS 14 and 15
  get the newest build published against the older toolchain. Previously
  the single pin targeted macOS 26 and died at dynamic-link time on
  anything older. A host older than every pin fails before download with
  the versions named; an explicit version: still wins.

Fixed

• Loading the admin UI no longer spends the admin rate budget. Static
  UI bundle assets are exempt from the per-IP admin rate limiter, so
  opening the dashboard cannot starve API polling behind 429s.
• sbproxy --version reports the real product version instead of a
  stale crate stub.
• The installer reports the binary it just installed, not whatever an
  earlier install left on PATH.
