Variable PreloadPriority`Const`

PreloadPriority: {
    CRITICAL: "critical";
    DEFERRED: "deferred";
    IMPORTANT: "important";
    NONE: "none";
} = ...

Preload priority levels for resource loading.

A frozen object rather than a TS enum, for the same reason as KernelErrorCode in errors.ts: an enum compiles to a runtime IIFE that no bundler can drop, so all four member names ship in the browser kernel even though every read is a constant. As a plain object the reads inline to their string values and the table itself is tree-shaken away.

The companion type alias keeps PreloadPriority usable in type position.
