app: move wayland mediation to shim package
test / test (push) Successful in 29s Details
Values used in the Wayland mediation implementation is stored in various struct fields strewn across multiple app structs and checks are messy and confusing. This commit unifies them into a single struct and access it using much better looking methods.

app: move app ID to app struct
App ID is inherent to App, and it makes no sense to generate it as part of the app sealing process.

app/share: fix order to ensure SharePath before any of its subdirectories
shareTmpdirChild happened to request an ephemeral dir within SharePath and was called before shareRuntime which ensures that path. This commit moves SharePath initialisation to shareSystem and moves shareTmpdirChild into ShareSystem. Further cleanup and tests are desperately needed for the app package but for now this fix will have to do.

app: port app to use the system package
