// This is the whole point of the C++ rewrite request: instead of a Flask web
// dashboard you had to open in a browser, the sniper is now controlled
// entirely from Discord with slash commands:
//
//   /start                       start watching all configured links
//   /stop                        stop watching
//   /status                      running state + per-link stock + totals
//   /links                       list configured links (with pause state)
//   /addlink url [label] [min_price] [max_price] [keywords]
//   /removelink url
//   /pause url                   toggle pause for one link
//   /scan url                    force an immediate one-off scan
//   /interval seconds            change the polling interval
//   /history                     last 15 scan results
//
// Uses D++ (https://dpp.dev/) for the gateway connection + slash commands.
