## Request

- Auth: one of:
  - API key in header `X-API-Key`

Save the calling user's Chat settings for this workspace: their default run-config knobs and/or their agent block list (the agents the Master may not delegate to). Use when the user changes a control in the Chat settings surface. A top-level PATCH — only the keys you send change; the block list applies to new Chat turns server-side.

## Request body

  - `run_config` object: Default Chat run knobs. Replaces the stored run_config wholesale when sent.
    - `depth` 'quick' | 'standard' | 'deep'
    - `actions_allowed` string[]
    - `on_question` 'pause' | 'auto' | 'none'
    - `external_search` boolean
    - `include_divergence` boolean
  - `blocked_agents` string[]: Agent slugs / refs the Master may NOT delegate to for this user. Empty = every agent usable.
