/**
 * Unified logger for daemon server and client.
 *
 * To improve the overall readability of the logs, we categorize things by "trigger":
 *
 * - [REQUEST] meaning that the current set of actions were triggered by a client request to the server
 * - [WATCHER] meaning the current set of actions were triggered by handling changes to the workspace files
 *
 * We keep those two "triggers" left aligned at the top level and then indent subsequent logs so that there is a
 * logical hierarchy/grouping.
