fix(lobehub,twenty,simplelogin): broken $STD fallback patterns

silent() hard-exits on non-zero return before || fallback executes.
Replace first $STD with plain redirect so fallback command can run:
- lobehub: dpkg -i || apt install -f (dependency resolution)
- twenty: yarn install --immutable || yarn install (lockfile fallback)
- simplelogin: npm ci || npm install (lockfile fallback)
