provider: Command Code's refusal of a Go plan's key says where the key works (#969, pan17) — a Go key added as the Command Code API-key provider (the preset, on api.commandcode.ai/provider) can never be served: Command Code's Provider API answers every request "Your Go plan doesn't include API access. Upgrade to Provider or higher …". APIError now adds that a Go key works through the Command Code plugin (Plugins › Command Code, signed in with the key), which asks as Command Code's CLI does. TestAPIErrorShapes and the new TestCommandCodeGoKeySaysWhereItWorks (chat, messages and responses through the gateway) fail without it and pass; go test provider/gateway/plugin/gui, vet, linux/windows builds pass.
