Save user edits to the latest draft of a specific type (GHOSTWRITTEN_EMAIL, FORWARDABLE_EMAIL, or TEXT) for an intro request. Call this when the user clicks Save in the editable email or text UI rendered from get_draft_by_type. Pass the full edited email_content or text_content (all fields, not just changed ones) and set is_manually_edited=true.

Use when: Use when the user edits a draft in the editable UI from get_draft_by_type and clicks Save — e.g. changes subject, body, To/CC, or the text message. Always set is_manually_edited=true. After saving: update the artifact in place with the saved content (do not re-fetch via get_draft_by_type unless the response content differs from what was submitted) and confirm success in plain language — e.g. 'Your edits to the Ghostwritten Email have been saved.' Do not explain tool names or internal state.

workspace_id / user_id are injected from request headers.

Next steps (after this tool succeeds): [optional] [SUGGESTION] → call intro_request_send_state_change_event: After editing, call intro_request_send_state_change_event with INTRO_REQUESTED_EVENT to submit the intro request for admin review.

Also returns pagination info (request_context).
