Point Chat machine flows to OpenVibe Link (#424)

OP OpenVibers committed 4 days ago · faaf71698b · 17 files, +64 −54

* Point Chat machine flows to OpenVibe Link

* Speak Link on the machine and provider paths

A paired machine token is a link principal (actor_type link), the desktop
party routes accept it, and the person's own-model provider is link in the AI
settings and the model picker, matching Contracts. The chat.preferences
fixture reports the namespace's current schema version.

* Merge remote-tracking branch 'origin/main' into rename/link-1109-Chat

* Merge remote-tracking branch 'origin/main' into rename/link-1109-Chat

* Merge main and pin openvibe-contracts v0.372.0

Keeps the link principal on the desktop party routes and the link provider in
AI settings, and moves the Contracts pin to the released Link tag.
