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.

Move the canonical local movement controller, body/motion managers, object clock, movement wire data, and MTS/jump/AP sender into AcDream.Runtime. Replace process skill defaults with typed Runtime character options, make graphical and direct commands borrow one autorun owner, retain the construction-time PartArray seam, and include movement in terminal ownership convergence.
Preserve the accepted pre-inbound movement/jump and post-inbound autonomous-position order while moving the exact packet/cadence fixtures into Runtime tests. Add graphical/direct parity, two-instance isolation, teardown, allocation, architecture, and divergence-path coverage.

Create the dependency-only Runtime project before moving any gameplay owner, enforce its direct, transitive, source, and load-time closure, and pin coherent lifetime-group extraction plus retryable teardown ordering. No production behavior changes in J0.
Validated by the four focused Runtime boundary tests, a zero-error Release solution build, and 8,406 passing Release tests with five pre-existing skips.
