 * v2.3 Phase 5 (design.md §7.3) — a SMALL curated catalog of ACP coding agents

 *
 * Non-goal: we never install anything. Each entry is a manual-install hint
 * (`installUrl` / `installCmd`) plus the config `command` that gets written into
 * `/data/coder-providers.json`. The user installs the CLI themselves; until the
 * binary is on PATH the provider shows as "Not installed". Commands are
 * editable after adding — versions are aliased/untrimmed on purpose; pin on your
 * own host once verified.
