Models per workspace: several providers, routed by kind of work

A workspace connects as many model providers as it uses (Anthropic, OpenAI, Google Gemini, and any Anthropic- or OpenAI-compatible endpoint) and routes each kind of work (making changes, reviewing, planning, catching up) to g1t's hosted models or to one of its providers and models. g1t's own routing stays fixed; the workspace's does not have to. The model proxy translates Anthropic's Messages API to OpenAI's Chat Completions and back, streamed tool calls included, so the one agent harness works with every provider and sandboxes still hold no key. Who may use agents is now the workspace's choice: one with its own provider can, at once; g1t's hosted models are open to listed workspaces until billing takes real money, then to all. The deploy-wide proxy flag is gone. Billing reads billedTo as the runner sends it.
