fix(test): e2e-harness-audit derives its skill census from disk

The hand-maintained 39-name SKILL_GLOBS list had drifted to 39 of 54
SKILL.md.tmpl on disk. No live gap today (none of the 15 unlisted
skills is interactive), but the next interactive skill would have
landed unguarded with zero signal. The audit now walks top-level dirs
for SKILL.md.tmpl (statSync so symlinked dirs like connect-chrome
count), so new skills are in scope the commit they appear.
