Port the sssf skill from ~/.agents/skills/sssf into this repo so it can be
distributed and installed with the skills CLI (skills add INDigitalStudio/skills
--skill sssf).
- Copy the skill (SKILL.md, cookbooks, references, scripts, templates, and the
visualizer app source) into sssf/.
- Gitignore build/runtime artifacts: the visualizer's node_modules/ and dist/,
Python bytecode, and the machine-specific repos.json.
- Make the skill location-independent: install.py now stamps the skill's real
path into the stamped justfile's skill_dir (replacing the hardcoded
~/.agents/skills/sssf), so 'just obs' finds the visualizer wherever the CLI
installed the skill.
- Update cookbooks to use <skill>/scripts/... instead of the hardcoded path,
and document the skills CLI install command.
- Update the repo README with install instructions.
