Back-merges master after #332 (release/1.4.11 windows-installer Smart App Control fix landed post-release). Brings that commit into develop per the normal release-train flow (release branch -> master -> develop).

BitHighlander and others added 6 commits June 19, 2026 21:47
release: v1.4.5 — swap UX, custom fees, build reliability fixes
release: v1.4.6 — Zcash shielded hardening + Windows installer fix
release: v1.4.10 — LTC portfolio stability, UTXO audit recovery, XRP REST signing, Hive onboarding
release: v1.4.11 — Hyperliquid EIP-712 colon-namespaced typed-data signing fix
…ck it

The default single-exe Inno installer self-extracts an UNSIGNED setup.tmp engine
to %TEMP% and runs it. Smart App Control (on by default on many Win11 machines)
blocks unsigned code, so v1.4.11 died with "Setup failed to initialize" (exit 1,
CodeIntegrity 3077/3033) and installed nothing. The EV signature on the outer
setup.exe doesn't help — SAC evaluates the extracted setup.tmp on its own, and
stock Inno can't sign it. The app binaries themselves are all EV-signed and
SAC-clean; only the installer's extracted stub was the problem.

Fix:
- installer.iss: UseSetupLdr=no -> no setup.tmp; the signed setup.exe is the
  engine and runs in-process, so SAC only sees the signed exe. Inno now emits
  setup.exe + setup-*.bin.
- build-windows-production.ps1: zip the parts into
  KeepKey-Vault-<ver>-win-x64-setup.zip and delete the loose exe/bin so a bare
  (SAC-blocked) single exe can't be shipped by accident.
- docs: WINDOWS-BUILD-AND-SIGN.md gains a "Smart App Control" section and a
  MANDATORY "install under SAC (Enforce)" checklist item — SAC-off machines are
  an invalid test, which is how this slipped through (1.4.7 smoke test was
  SAC-off). Full write-up in docs/incidents/.

Validated on a SAC-Enforce machine via the real download flow (zip + MotW ->
extract -> run setup.exe): exit 0, version 1.4.11, no 3077/3033, app boots.
