So much passing of the `linkAction` to only then give up halfway through
and reimplement it locally again down in the overflow popover.
This materially matters now because mapper tags are searched as plain
words and user tags are searched using the `tag=""!` syntax.
The way that this works is that it plugs into the online request to
retrieve the beatmap set that the client is already performing, and
stores user tag data to the local realm database.
This means that for now user tags will only populate for beatmaps that
the user has displayed on song select which is obviously subpar. I plan
to follow this change up by adding user tag state dumps to `online.db`
and using that data for initial tag population to make the majority case
(ranked beatmaps) work.
Note that several decisions were made here that are potential discussion
points:
- `RealmPopulatingOnlineLookupSource` is set up such that it can be the
middle man / redirection point for similar flows that we need and we
are currently missing, such as storing guest difficulty information,
or storing the user's current best score on a beatmap (handy for rank
achieved sorting / filtering / etc.)
- The user tags are stored in `BeatmapMetadata` which breaks the
longstanding assumption that you can arbitrarily pull out a metadata
instance from any of the beatmaps in a set and get essentially the
same object back.
I've attempted to constrain this some by not adding user tags to
the `IBeatmapMetadataInfo` interface through which `BeatmapSetInfo`
exposes metadata further, but I warn in advance that this is
a temporary state of affairs and I will make it worse in the future
when `BeatmapMetadata.Author` becomes `Authors` plural in order to
support guest mapper display (and direct guest difficulty submission).
- The syntax for searching via user tags is chosen to mostly match web -
it's `tag=`, with support for all of the string matching modes song
select already has (bare word for substring, `""` quotes for phrase
isolated by whitespace, `""!` for exact full match).
In stable mania, Hard Rock and Easy mods do not work the same way as
they do on all of the rulesets. The difference is that mania HR and EZ,
rather than apply a multiplier to the map's original Overall Difficulty,
apply multipliers to *the durations of hit windows themselves*.
Prior to the last release, lazer was oblivious to this reality and just
treated mania HR / EZ as it did every other ruleset. Last release, for
the sake for gameplay parity across rulesets, the mods in question were
adjusted to match stable, but in the process, it started looking like HR
/ EZ did not change OD anymore.
The problem is that they do, but applying a multiplier to the map's OD
and applying a multiplier to the hit window duration is not the same
thing. The second thing is actually *much harsher* in magnitude, to the
point where applying HR to any map is almost guaranteed to exceed "the
effective OD" of 10, and applying EZ to any map is almost guaranteed to
result in "negative effective OD".
This change attempts to convey that reality by displaying "effective
OD", similar to what's already done in other rulesets when rate-changing
mods are active. Note that the values this will display *do not match*
stable *and that is correct*, because stable song select *lies* about
the actual impact on OD by just assuming it can treat all rulesets in
the same way.

Would close https://github.com/ppy/osu/issues/34150 I guess.
And yes I would like *all of the above* to land on the changelog if
possible if this is merged.
