LLM-agent install

The full playbook lives at .claude/skills/install/SKILL.md. Paste the snippet below into any compatible coding agent:

Install the Swiss River Network Benchmark by cloning
https://github.com/jajupmochi/swiss-river-network-benchmark.git into the
current directory, running `uv sync --no-cache --all-extras`,
smoke-checking with `uv run pytest -q`, and then starting the Streamlit
UI via `uv run srn app streamlit`. Read .claude/skills/install/SKILL.md
for the complete playbook before starting.

Compatible agents:

• Claude Code (picks up the skill automatically via .claude/skills/).
• OpenAI Codex, Gemini CLI, GitHub Copilot CLI — follow the SKILL.md steps as a checklist.

The playbook covers prerequisites, install, CLI / GPU / package smoke tests, and UI launch — every step is idempotent.
