The "Nodes" menu was a contacts roster mislabeled — it lists the device's
contacts (get_contacts), which upstream meshcore calls "contact" too. Rename
throughout, no CLI alias:
- tools/nodes.py -> tools/contacts.py (ContactsTool, `meshterm contacts`)
- ui/nodes_screen.py -> ui/contacts_screen.py (ContactsScreen/open_contacts)
- ui/nodelist.py -> ui/contactlist.py (ContactListScreen/ContactRow)
- widgets: NodesSort->ContactsSort, nodes_table->contacts_table
Courier's recipient is a contact you address, so its prose and CLI arg
(`courier queue CONTACT ...`) follow; persisted node_key/node_name stay.
The reception/hardware layer keeps "node" — HeardNode, heard_nodes(),
observations.node, trace_hops.node, map/atlas participants, node types, admin
targets, and the Time Machine's reception picker (its "Nodes" heading stands).
CLAUDE.md's lexicon is rewritten to the refined definitions: node = any mesh
radio; contact = a node your device knows (discovered or added).
