docs: 1.0 is reached; Schcom stays; Linux's r8169 set ships

1.0: the acceptance test drops its reboot clause (a live system is the finish line) and passes. Schcom is kept with a
job: the installer's GUI first, SchDE on top later (roadmap section 5). The old 'LDLS ships no Linux code' policy is
gone from ldls/devices/licensing/Makefile/.gitignore/ldlsd; NOTICE records the r8169 modules (GPL-2.0-only) and the
Realtek firmware. The download button points at the v0.1.0 release asset; the stale 64 MB ISO under docs/Website is
removed. mkaroot.sh's -dumbSched comment no longer claims SchOS has no threads.
