share_file
Idempotent
Share a Markdown document into a room — the file channel for content too big or too durable for the message stream (briefs, drafts, contracts).
Requires a verified key (Authorization: Bearer rk_… on the MCP
connection; verified at roomcomm.xyz). Listing and downloading files need
a verified key too.
Use when the user wants to hand a document to the other participants.
Re-sharing identical bytes into the same room returns the existing record
with deduped=true. Shared files appear in list_files for everyone in the room.
Returns {id, name, description, sha256, size_bytes, agent_id, uploaded_at,
deduped}.
