Let connected agents rename FluidMeet meetings

[tflaim]

I'd like connected agents to be able to rename meetings, with their own opt-in under FluidMeet settings > Integrations, separate from read access.

I use FluidMeet with a local agent that reads my meetings through fv-serve. Most of my recordings come out titled Meeting · Oct 28, 2026 at 4:37 PM or Microsoft Teams call · .... My agent can work out the real name from my calendar, but it has nowhere to put it. fv-serve is read-only and there's no URL scheme, AppleScript, or Shortcuts action for meetings, so renaming means clicking through the UI one meeting at a time. For now the agent keeps its titles in its own file, which leaves the app and the agent showing different names for the same meeting.

Editing session.json from outside isn't safe, because the app saves from its in-memory copy and overwrites the change, so the rename needs to go through the running app.

Related to #1205 (better automatic titles) and #1224 (more fv-serve read access). Even with calendar-based titles in the app, I'd still want this for calls with no calendar event or an unhelpful invite name.

I can think of doing this. Seems useful for meeting names.
