* Open the studio's SDK session with master-view semantics.
*
* The master view has no explicit comp path, but the session must still model
* the project's main composition so schema-level panels (Variables, Slideshow)
* work there. Edit-flow consumers keep the legacy "no session on master view"
* gating via `editFlowSdkSession` so cutover behavior is unchanged.
*
* Also clears preview variable overrides whenever the composition or project
* changes — overrides are per-composition and must never leak into another
* composition's preview or render.
