Lock in teaming team MCP tool

Operates in the cross-company GovTribe teaming network. Lock in a finalized team for a PRIME teaming interest. Requires at least one accepted match on the prime. Withdraws every PENDING inbound match request on the prime (those subs are notified their request was withdrawn), transitions the prime to matched, opens the team-hub conversation, and notifies accepted subs. From the agent, the only way back is `Disband_Teaming_Team` (which has wide blast radius). Prime-only. Before calling, name the accepted sub partners + the count of pending requests that will be withdrawn to the user and obtain explicit confirmation.
