Add per-model council settings, Quick Chat council mode, and per-member trace selection

Council members now support individual temperature, reasoning effort, web search, and
context trace overrides. Quick Chat inherits council config from the source node and
streams through the 3-stage council pipeline. Blueprint loading migrates old string[]
council formats to CouncilMemberConfig[].
