Initial commit: apkovl deployment source, synced from shell-project main

This directory is what gets packaged into localhost.apkovl.tar.gz and
baked into adaptiveos-vN.iso. It had drifted out of sync with the real
project (root/shell-project/ had gone missing entirely at some point
after being written earlier this session -- cause unconfirmed, Desktop
is a plausible sync-related suspect but not verified) and separately
carried a stale, pre-fix copy of fx.sh.

Current contents:
  etc/profile.d/adaptive-loop.sh   -- disk-persists p AND p.trace
                                       (fx()'s fix-provenance record)
                                       across reboot, two separate 1MB
                                       blocks on the attached state disk
  etc/profile.d/adaptive-setup.sh  -- unchanged, network/git/fzf bring-up

                                       shell @ 3c4947e (main), plus three
                                       deployment-only files not in that
                                       repo: contrib/fx/builtin-fixes.txt,
                                       contrib/fx/sources.d/15-builtin-
                                       fixes.sh, contrib/heal/heal.sh

Verified byte-identical to what's actually embedded in the currently
shipping adaptiveos-v6.iso before this commit (full recursive diff),
and every .sh file passes `sh -n`.

.gitattributes (text=auto eol=lf) added to prevent the CRLF corruption
that hit the canonical repo earlier this session from recurring here.
