feat: add execution source field + improve Slack is_member docs

- Add source and originExecutionId to bubbleFlowExecutionSchema for
  tracking which surface triggered an execution (mcp, web-pearl, etc.)
- Improve Slack list_channels/get_conversation_history descriptions to
  guide agents on is_member filtering and join requirements
