Adding a new agent

Create src/agents/<name>/mod.rs and implement the Agent trait (including is_installed, so suivi init only targets machines that have the agent)
Add hook template files under src/agents/<name>/hooks/
Register it in all_agents() in src/agents/mod.rs

The agent must provide a session_id in its hook payload — this is required for correct per-session tracking.
