fix: alias-only files missing from full packs

find_undeclared_files was enriching declared_names with DB aliases,
filtering core extras that were never packed by Phase 1 under that
name. Pass strict YAML names to _collect_emulator_extras so alias-
only files (dc_bios.bin, amiga-os-310-a1200.rom, scph102.bin, etc.)
get packed at the emulator's expected path. Also fix truth mode
output message and --all-variants --verify-packs quick-exit bypass.
