Vendor the two local Rust crates that build the lite backend artifact into third_party/silentdragonxlite/ (the qtlib C-ABI wrapper + the silentdragonxlitelib core, with proto/res and all the lite-send fixes), and point build-lite-backend-artifact.sh's default --backend-dir there, so the lite wallet builds without the upstream SilentDragonXLite repo. External build inputs are now only the Rust toolchain + git.dragonx.is + crates.io: - the 6 librustzcash git deps point at the git.dragonx.is/DragonX/librustzcash mirror (pinned rev acff1444), not git.hush.is; - the Sapling params are gitignored (not committed, no Git LFS) - the build fetches them from the git.dragonx.is/DragonX/zcash-params 'sapling-v1' release and verifies their SHA-256 before rust-embed bakes them in (ensure_sapling_params). For fully offline builds, cargo vendor into lib/vendor/ and add a vendored-sources redirect (vendor/ is gitignored; the script symlinks it into the prepared dir).
