fix(siriusxm): remove unused request-promise import

[garrettwinder]

Summary

• Remove the unused request-promise import from lib/actions/siriusXM.js.
• The request variable was never referenced anywhere in the file, so the import was dead code.
• request-promise is pinned to ^0.0.1, a long-abandoned package whose main field points to a missing lib/tp.js. Because lib/helpers/require-dir.js loads every file under lib/actions at startup, this broken require was crashing node server.js on startup.

Test plan

• Confirmed lib/actions/siriusXM.js loads cleanly when request-promise resolution is blocked:

  node -e "const M=require('module');const o=M._resolveFilename;M._resolveFilename=function(r,...a){if(r==='request-promise')throw new Error('blocked');return o.call(this,r,...a)};require('./lib/actions/siriusXM.js');console.log('OK')"
  

• Note: two other files (musicSearch.js, spotifyDef.js) also require request-promise and are being fixed in parallel PRs. node server.js will continue to crash until all three are merged.
