fix: cover the gitignored clawhub SKILL.md in dispatch tests only when present

clawhub-upload/SKILL.md is gitignored and absent on a fresh clone, so the
five Stop-scalar shape tests raised FileNotFoundError on every CI leg while
passing locally. Same present-only convention as
test_skill_frontmatter_valid.py. The scalar behavior tests passed on all
three legs, including the first macOS run, so the v3.8.0 dispatch fix
itself is verified on every platform.
