Move request selection and lifecycle updates to the UI thread so worker jobs only build their assigned asset and hand back a completion. This removes request-map locking and keeps priority promotion, cancellation, and publication under one thread's ownership. Limit outstanding jobs to half the reported hardware threads, with a minimum of one and no fixed cap. Release job slots before texture dependency settlement and retain completion wakeups for synchronous waits, pause, and shutdown. Share piece-request cleanup while preserving in-flight load holds. Use cancelled request states to suppress invalidated notifications instead of an obsolete flag. Clarify function names, document the lifecycle, and group header declarations. Validation: Qt Debug build, scheduler and lifecycle harness, one-slot texture success/retry checks, notification suppression and reference checks, 14 asset exports, and git diff --check passed.
