Tool calls

Expand apps/gallery/src/patterns/agent.rs

What looked like a component — a "tool group" — is slice::chunk_by over consecutive calls of the same verb:

for run in CALLS.chunk_by(|a, b| a.verb == b.verb) {
    // one row, or a folded group of them
}

bezel wrote nothing for that. The rows are widgets::step_row, the output under an open row is widgets::step_output, and the grouping is std.

The two shapes are here as well, and they are not a parameter anywhere in the library: a lone call is a bordered card, a grouped one is a bare row, and the group's box owns the border and the hairlines between its rows.

step_row takes strings, so bezel never learns what a tool call is. The icon, the verb, the detail and the duration are the app's vocabulary; the row is the shape they share with a CI step and a migration.
