ML-69	ArgumentError raises in ScrobbleActivity	To Do		2026-04-20 08:55			https://github.com/cloud8421/music_library/issues/106	low

Description

lib/music_library/scrobble_activity.ex:19,61,116 raises ArgumentError when both started_at and finished_at are provided to scrobble functions. Per Elixir conventions, public API functions should return {:error, _} tuples for input validation rather than raising. These functions are called from LiveComponent event handlers where a crash would kill the LiveView process.

Expected behavior

Return {:error, :invalid_options} (or similar) and handle upstream with a user-facing toast message.
