This is implementing the segments events for delta API. Previous version
of delta API, we were just sending all of the segments. Now we will have
`segment-updated` and `segment-removed `events coming to SDK.
We are changing how the Delta API works, as discussed:
1. We have removed the `updated` and `removed` arrays and now keep
everything in the `events` array.
2. We decided to keep the hydration cache separate from the events array
internally. Since the hydration cache has a special structure and may
contain not just one feature but potentially 1,000 features, it behaved
differently, requiring a lot of special logic to handle it.
3. Implemented `nameprefix` filtering, which we were missing before.
Things still to implement:
1. Segment hydration and updates to it.
Weird thing is that I could not reproduce it locally, but I have a
theory to fix our delta mismatch.
Revisions are added to the delta every second.
This means that in a single revision, you can disable an event, remove a
dependency, and archive it simultaneously. These actions are usually
performed together since archiving an event will inherently disable it,
remove its dependencies, and so on.
Currently, we observe these events happening within the same revision.
However, since we were checking `.updated` last, the event was always
removed from the `removedMap`.
Now, by checking `.removed` last, the archive action will properly
propagate to the revision.
Our delta API was returning archived feature as updated. Now making sure
we do not put `archived-feature `event into `updated` event array.
Also stop returning removed as complex object.
Trying again, now with a tested function for resolvingIsOss.
Still want to test this on a pro instance in sandbox before we deploy
this to our customers to avoid what happened Friday.

When there is new revision, we will start storing memory footprint for
old client-api and the new delta-api.
We will be sending it as prometheus metrics.
The memory size will only be recalculated if revision changes, which
does not happen very often.
This is still raw and experimental.
We started to pull deleted features from event payload.
Now we put full query towards read model.

This PR refactors the method that listens on revision changes:
- Now supports all environments
- Removed unnecessary populate cache method
# Discussion point
In the listen method, should we implement logic to look into which
environments the events touched? By doing this we would:
- Reduce cache size
- Save some memory/CPU if the environment is not initialized in the
cache, because we could skip the DB calls.
This is based on the exising client feature toggle store, but some
alterations.
1. We support all of the querying it did before.
2. Added support to filter by **featureNames**
3. Simplified logic, so we do not have admin API logic
- no return of tags
- no return of last seen
- no return of favorites
- no playground logic
Next PR will try to include the revision ID.
This is not changing existing logic.
We are creating a new endpoint, which is guarded behind a flag.

Added more tests around specific plans. Also added snapshot as per our
conversation @gastonfournier, but I'm unsure how much value it will give
because it seems that the tests should already catch this using
respondWithValidation and the OpenAPI schema. The problem here is that
empty array is a valid state, so there were no reason for the schema to
break the tests.
I've tried to use/add the audit info to all events I could see/find.
This makes this PR necessarily huge, because we do store quite a few
events.
I realise it might not be complete yet, but tests
run green, and I think we now have a pattern to follow for other events.

`@gitar-bot cleanup stale_flag=value` will cleanup a stale feature flag.
Replace `stale_flag` with the name of the stale feature flag and `value`
with either `true` or `false`.

Now frontend API requests will be counted separately under
getAllByfrontend. We are already tracking new FE db calls, so we can
build grafana dashboard.
## About the changes
Queries on client-feature-toggle store have many purposes depending on
the requestType, making the query more complex or not depending on the
use case. Also, each use case has different frequencies (i.e. playground
is expected to be used rarely).
The name for the store metrics was wrong, copy&pasted from:
7b04db0547/src/lib/features/feature-toggle/feature-toggle-store.ts (L107)
Which was also present in feature-tag metrics:
7b04db0547/src/lib/db/feature-tag-store.ts (L37)
With this, we'll have more granularity to understand the execution time
and frequency of each
Lots of work here, mostly because I didn't want to turn off the
`noImplicitAnyLet` lint. This PR tries its best to type all the untyped
lets biome complained about (Don't ask me how many hours that took or
how many lints that was >200...), which in the future will force test
authors to actually type their global variables setup in `beforeAll`.
