- Around line 303-330: Update the settled calculation in
GameViewSizeControl.Read so any created render texture is considered settled,
even when its dimensions differ from targetSize. Preserve the existing
matches_requested comparison so a capped texture can complete readback and
report false when it does not match the requested size.

Description
Adds fixed Game View resolution control for layout verification. A request for 2400 × 1080 now selects a reusable MCP preset and waits for the allocated render target to match Unity's computed size. The response reports requested, selected, computed and allocated dimensions separately, so a preset selection cannot be mistaken for a successful render-size change.
Type of Change
Changes Made
Compatibility / Package Source
Testing/Screenshots/Recordings
Manual graphical checks confirmed 2400 × 1080 and 1080 × 2400 allocated textures, with matching readback and unchanged focus, window geometry and display scale. A hidden Game View returned the five-second timeout with the newly selected size and its still-old allocated texture. Multiple open views with neither focused returned an ambiguity error without selecting a preset. The test fixture restored its original presets and shared preference values afterward.
The focused tests cover preset reuse, unrelated/user-edited preset preservation, corrupt ownership records, per-group ownership, validation, closed-view/busy behavior and concurrent preset edits. They are not the full Unity project test suite.
Documentation Updates
Related Issues
Relates to #1436. Implements the fixed-dimension first step discussed there. Named/aspect-ratio presets and temporary screenshot-size switching are outside this PR.
Additional Notes
Unity stores these presets globally across projects. The command changes only its recorded preset; if the user edits it, the next resize preserves that entry and creates a new owned one.
A timeout can leave the requested preset selected. The response says so and includes the observed dimensions. GPU limits may also reduce the actual size. Allocated dimensions establish the render-target size, not the freshness of its pixel content. Unity's internal Game View APIs are isolated in one Editor helper and return an explicit unsupported-version error if the required API is unavailable.
