William P a44bb1bf34 optimize codebase ...

main.go:
- Eliminated ~160 lines of duplicate code: Extracted 3 new helper functions at the bottom of the file:
buildVideoMenuOptions([]VideoOption) — builds the Discord select menu options for video formats
buildAudioMenuOptions([]AudioOption) — same for audio
fetchAndShowFormats(s, i, url) — fetches formats, sorts them, builds menus, stores state, and edits the interaction; previously duplicated identically in both the download and download video command handlers
- Fixed time.Sleep ordering bug: The startAsyncDownload goroutine was launched before InteractionRespond with a 100ms sleep to compensate. Now the download is launched after InteractionRespond returns — no sleep needed. Removed "time" import.
- Used helpers in video_select handler: The two inline menu-building loops in that handler now call buildAudioMenuOptions / buildVideoMenuOptions

misc.go:
- Moved regexp.MustCompile(...) to a package-level var urlPattern — previously it recompiled the regex on every call to extractURLFromString
- Simplified the function body to a single return line
