feat(project): ProjectOverview endpoint

[constantinius]

Contributes to https://github.com/getsentry/projects/issues/755

The idea is to have an endpoint that quickly responds with mininimal project info to make the polling of newly created projects as efficient as possible.

This new endpoint only includes data of the actual project, no additional lookups or metrics extraction is made.

This can easily get outdated because we often add new fields to the project response, can we not reuse ProjectSerializerResponse?

[constantinius]

We could, even if we will never set some of the fields. But that should be okay, as ProjectSerializerResponse has total=False

[constantinius]

No, seems we cannot:

$ mypy src/sentry/api/endpoints/project_overview.py
src/sentry/api/endpoints/project_overview.py:81: error: Missing keys ("isBookmarked", "isMember", "features", "access", "hasAccess") for TypedDict "ProjectSerializerResponse"  [typeddict-item]
Found 1 error in 1 file (checked 1 source file)

[vgrozdanic]

What about inheriting from that serializer and marking it total=False?

[constantinius]

That works! TIL

[constantinius]

Nope, my mistake it actually does not work: https://github.com/getsentry/sentry/actions/runs/13652215539/job/38163221839?pr=86175#step:5:16

[constantinius]

Also not with shenanigans like

class ProjectOverviewResponse(ProjectSerializerResponse, TypedDict, total=False):
    pass
