Opus dual-lens review of cb6502c8 passed with six findings; this lands
the fix round:
1. headless-portability.yml: AcDream.Platform src/tests join both path
triggers and the presentation-free build/test arrays — the moved XDG
tests run on ubuntu-latest again (they had fallen out of every Linux
lane).
2. acdream-architecture.md: AcDream.Platform gets its own layer block;
Runtime may-reference clause updated (the guard changed in cb6502c8,
its human-readable twin had not).
3. PlatformDependencyBoundaryTests: the BCL-only contract (zero
project/package references) is now enforced, not just observed.
4. memory/project_linux_graphical.md canonical seam renamed.
5. Plan LA0 recon corrected: the K0 Headless guard was never the guard
needing amendment (it asserts Headless own refs); Runtime own-refs
guard was — the commit did the right thing, the plan text now says so.
6. App declares its AcDream.Platform reference explicitly per its own
convention instead of riding transitivity.
Platform.Tests: 4 passed (3 moved + the new guard).

The launcher (LA3/LA4) needs the XDG/Windows path contract
(ApplicationPathSet/IApplicationPathEnvironment) without pulling in any
gameplay assembly. Move it out of AcDream.Runtime into a new BCL-only
AcDream.Platform project so the launcher-side Launcher.Core project can
reference it directly per the campaign plan (docs/plans/2026-08-14-launcher-campaign.md,
LA0). Namespace renamed AcDream.Runtime.Platform -> AcDream.Platform;
code is otherwise byte-identical (no logic changes).
AcDream.Runtime now carries a ProjectReference to AcDream.Platform and
re-exports it transitively, so App and Headless keep resolving the type
without a direct reference and K0's Headless single-ProjectReference
guard (HeadlessAssemblyReferencesOnlyTheRuntimeProject) stands unchanged.
The sibling Runtime dependency-boundary guard
(RuntimeProjectDeclaresOnlyApprovedProjectDependencies) does assert
Runtime's own project-reference set, so it needed a deliberate,
documented addition of AcDream.Platform to its expected list.
Moved tests/AcDream.Runtime.Tests/Platform/ApplicationPathSetTests.cs to
a new tests/AcDream.Platform.Tests/ project (namespace
AcDream.Platform.Tests) referencing only AcDream.Platform. Registered
both new projects in AcDream.slnx.
