The shell `find ~/.hermes/skills ~/.hermes/hermes-agent/optional-skills ...`
snippet hardcoded a dev-clone path that does not exist on user installs; the
loader already substitutes ${HERMES_SKILL_DIR} (skills.template_vars), which
is what every other bundled skill uses. Drop the upstream-agent path mention.
Regenerated the docs page so it matches SKILL.md (also fixes the comfyui
related-skill link, which now lives under optional).
