Harness spec 3.6.0: phone_action, done on the person's phone and confirmed there

harness/phone.md, tools/phone_action.json, loop.json phone, conformance/phone.json.
The LLeMbas server's tool alone (scope llembas, sessions chat), offered once a
message came from the LLeMbas app with the capability phone_actions (new
requirement phone). Actions: alarm, timer, calendar_event, sms_draft,
email_draft, dial, navigate, add_stop, search_nearby, stop_navigation,
open_app, open_url, media, torch, settings_panel, automation_intent. Each
reads its own fields; required fields and value checks give the call's
refusal in the spec's words. The person confirms on the phone every time;
the result is done, declined or failed with what the phone said, or no
answer in time. add_stop carries the route's destination: no map app adds
to a running route, so the phone plans again via the stop.
