patch-dsc-maxslide self-gates to a no-op when the shared cache fits the
vphone600 26.x kernel's 6 GiB region, which 26.x/18.x bases always do, so
it only fires on 27. Add a --force flag that bypasses the fits-check and
zeroes maxSlide unconditionally (still idempotent), and a
FORCE_DSC_MAXSLIDE=1 env opt-in in cfw_install.sh that runs it on non-27
bases. Default off; 27 behavior unchanged.
Also fix the installer env-threading in cfw_install_host.sh: a
${VAR:+NAME=val} word produced by expansion is not parsed as a shell
assignment (zsh runs it as a command), so route the assignments through
env. This makes FORCE_DSC_MAXSLIDE reach the installer and repairs the
same latent bug for SPOOF_BUILD.
Verified on a 26.4 JB VM: FORCE_DSC_MAXSLIDE=1 yields on-disk maxSlide=0
and a live shared-cache slide of 0x0 (dyld maps the cache at its
preferred base 0x180000000 in rpcserver_ios), versus the nonzero slide a
stock 26.4 boot picks.
Docs + research/0_binary_patch_comparison.md updated (README and the ja/ko/zh
translations).
