/dd_update — Deep Desert updater controls
Manage the weekly “Deep Desert — Weekly Uniques” message updater for this guild.
Usage
/dd_update <action> [reason]
  action — stop | resume | start 
  reason (optional) — free text appended to the confirmation response. 
Permissions
  - stop / resume: Server Owner or members with Manage Server.
 
  - start: Server Owner only. Use with care—this forces an immediate check cycle.
 
Behavior
  - Weekly reset: Tuesdays 03:00 UTC. At reset, the bot updates the channel message to indicate it’s waiting for the new week.
 
  - Polling cadence: adaptive back-off until fresh data is found:
    
      - Every 5 min for the first hour
 
      - Then every 15 min until 3 hours
 
      - Then every 30 min until 6 hours
 
      - Then every 1 hour until 24 hours
 
      - Then every 3 hours
 
    
   
  - Success: when new valid data appears, the bot updates the message once and idles until the next weekly reset.
 
  - Errors / no update yet: the message shows a generic notice that it’s still waiting or that an issue occurred (no external source is mentioned).
 
Actions
  - stop — Pauses all checks. The message remains as-is until you 
resume. 
  - resume — Returns to the normal weekly cycle (detect reset, then poll until new data).
 
  - start — Pretends the weekly reset just happened and begins polling now. Owner-only.
 
Channel & config
  - Target channel: taken from 
SHAI_DD_CHANNEL_ID (env). If unset, defaults to 1404764793377652807. 
  - Scope: guild-specific. The message lives in this server’s configured channel.
 
Notes
  - This command only controls the updater; it does not manually edit the posted message.
 
  - On each successful weekly update, the bot compares content against the previous week to avoid duplicate posts.
