fix(social-discord): set wait query parameter

[aiirvizionz]

Summary

• build Discord webhook URLs with URLSearchParams instead of string-appending wait=true
• replace an existing wait=false value with wait=true
• preserve thread routing and any other existing webhook query parameters

Tests

• ./node_modules/.bin/vitest.CMD run packages/social/discord/src/index.test.ts
• ./node_modules/.bin/tsc.CMD -p packages/social/discord/tsconfig.json --noEmit
