httpwg

Chair tooling for the IETF HTTP Working Group (httpbis). Use whenever a chair wants to build, rough in, revise, or set times on an httpbis IETF meeting agenda — e.g. "start the IETF 126 agenda", "/httpwg agenda", "add Resumable Uploads to the agenda", "fix the times on the agenda", "who do we need to email about the agenda". Currently implements the `agenda` subcommand. Requires the ietf-llm MCP tool and access to the chair's email (to compose the call-for-presenters draft).
