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 root/shell-project/ -- synced from space.seodr.ovh/ Daveswo/self-healing-autopoietic- 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.

+# PATH-fuzzy source: if the first word isn't a known command, alias, or
+# function, offer a function wrapping the closest-spelled real command
+# as a candidate -- as a fix you approve through the normal f() flow,
+# not a silently auto-installed hook. A function, not an alias: aliases
+# only expand in interactive shells (need `shopt -s expand_aliases`
+# otherwise), so an alias-based fix silently does nothing when f/fx run
+# inside a script.
+#
+# Pure POSIX: walks $PATH directly instead of `compgen -c`, which is a
+# bash-only builtin and does not exist under busybox ash -- this source
+# used to be dead weight on exactly the minimal/embedded shells this
+# project targets. Tested against busybox ash + busybox awk directly,
+# not just bash + gawk.
+#
+# Uses Damerau-Levenshtein-lite (edit distance + adjacent transposition)
+# so the canonical "gti" -> "git" typo scores 1, not 2 -- plain Hamming
+# or substitution-only distance ties it with unrelated 3-letter commands
+# like "ftp" and can pick the wrong one.
