The find -> sort -> read chain in both scripts used newline-delimited
records (plain read -r), so a skill directory name containing a
literal newline would be split across two records. Verified with a
directory literally named "evil\nskill": the old reader produced a
truncated "evil" fragment plus an orphan "skill/SKILL.md" fragment,
inflating the skill count and throwing awk/date errors on the garbage
paths.
Switch to -print0 / sort -z / read -r -d '' in both scripts so a path
is always read as a single record, regardless of its contents. Paths
under scan are untrusted input.

Following up on the -L fix: find -L can now traverse symlinks, but a
broken symlink target or an unreadable directory makes find skip that
entry and exit non-zero. Both scripts previously redirected find's
stderr to /dev/null and never checked its exit status, so a scan could
silently under-count skills with no indication anything was wrong.
Capture find's exit status and stderr in both scripts; on failure,
print a warning (with the underlying find error) to stderr while still
emitting the best-effort results for whatever was found. Verified with
a permission-denied skill directory: real BSD find exits 1 and reports
"Permission denied" on stderr, now surfaced as an explicit warning
instead of silently dropped.

scan.sh and quick-diff.sh both used `find "$dir" -name "*.md" -type f`,
which missed symlinked skill directories (no -L) and miscounted any
non-skill markdown file sitting in a skills directory as a skill
(matched *.md instead of SKILL.md). Both call sites now use
`find -L "$dir" -name "SKILL.md" -type f`.
Repro (temp dir with 1 real skill, 1 symlinked skill, 1 stray .md file):
before: 2 skills found (real skill + the stray .md, symlinked skill invisible)
after: 2 skills found (real skill + symlinked skill, stray .md excluded)
Fixes#2598
