Changed timed difficulty attributes to be "per-HitObject" instead of "per-DifficultyHitObject"

[Givikap120]

Before, timed difficulty attributes was bound to difficulty hit objects. This caused bugs like this:

osu.2024-06-16.17-10-17-591.mp4

As we can see here, spinner is using difficulty attributes from the second object, making it appear like the spinner itself gives 19pp.
Changing timed difficulty attributes to calculating per beatmap hitobject make it correct:

osu.2024-06-16.17-11-07-225.mp4

By commit you mean first and only commit named "fixed the bug"? Because PR name seem descriptive to me as it exactly what PR does: calculating difficulty attributes for each hit object instead of for each difficulty hit object

Fix the red crosses shown below.

Commit messages are as important - if not more than - PR titles so please give both due considerations.
