Function observe 

fn observe(
    store: &Store,
    block_id: &str,
    tool_use_id: &str,
    label: &str,
    owner: Option<&str>,
    started_at_ms: i64,
    seen_at_ms: i64,
) -> bool

Create the row if needed, then record the CLI’s description as its label (replacing the renderer’s generic “Bash” if it got there first) and its owner.
