5c157e8400 Build the GPU compositor off the UI thread (#9969)
* Prepare GPU compositor in background

* Add compositor startup performance scenarios

* Generate scorecard in scratch CI

* Fix pipeline build type inference

* Address compositor startup review and document measurements

* Run startup performance checks on scratch CI

* Remove scratch performance job

* Count failed GPU attempts in frame timing

* Make shader fingerprint test portable

* Address review: run first-document scenario as a guarded group; share COMPOSITOR_BUILDING constant

* Handle compositor startup benchmark failures

* Fix frame timing after upstream merge

* Keep GPU startup failures on CPU fallback

* Record the failed GPU attempt of a deferred redraw, and bound --reps

A redraw deferred after a failed GPU composite carries that attempt's time to its end, where it is
recorded once beside the CPU time. Perf::record clears the attempt so a direct CPU refresh doesn't
inherit the last one's. perf_scenarios caps --reps.

* Refresh cached canvases after compositor build

* Expose canvas cache key to GPU completion handler

* ci: drop the GPU compositor probe job

AGENTS.md: feature and fix PRs don't add or change CI, and app workflows
only call the shared craft-common-actions workflows. The probe example
stays as a manual tool (cargo run -p photocraft-gpu --example
compositor_build_probe).
