Operator decision: backend env hard-coding a single guild/channel was
wrong. Center can host multiple guilds, each can have multiple
announce channels for different purposes. The proposing agent picks
which one this topic broadcasts to.
dialectic_propose_topic tool schema adds:
- announce_guild_base_url (string, optional)
- announce_channel_id (string, optional)
- both or neither - one-of-two rejected at backend POST time
- omit both - topic has no broadcasts (agents must poll detail)
Tool description points agents at "Fabric channel-list tools" for
candidate discovery. Workflow docs spell out the discovery pattern.
