"""The classic CLI's `/toolsets` and `/platforms` reports as plain lines.

Shared by the classic CLI (`CLIInfoMixin.show_toolsets` / `_show_gateway_status`) and the shared
gateway, which runs the same report for a local session's `slash.exec` (gateway/session_info_reads.py):
one text on every surface, read where the state lives (the session's toolsets, the gateway's
platform config).
