test: cover lifetime and diagnostic ownership of a [Module]'s self-compiled [Scan]

[vbreuss]

Two acceptance criteria of the self-compiled module scan were implemented but never asserted.

Lifetime: ScanLifetimeModule in the referenced support assembly self-compiles two scans, one Singleton and one Transient, over internal matches exposed only through their interfaces. ModuleScanLifetimeTests imports it and asserts a singleton match is one instance per Root (shared across that root's scopes, distinct between roots) while a transient match is a new instance per resolve. The existing coverage stopped at the emitted Lifetime = on the generated registration and never observed the container honoring it at runtime.

Diagnostic ownership: PerMatchScanDiagnosticsLandInTheLibrarysBuildAndNotTheConsumers runs the generator over a library whose scan matches one type with an accessible exposure interface and one with only an internal one, then compiles a consumer against the emitted assembly. The library build reports AWT196 on its own [Scan] line naming its own type; the consumer build reports nothing while still binding the exposable match. This is what evaluating the scan in the module compilation buys, and only the same-compilation case was covered before.
