Motivation

• Provide a simple hook-based API to resolve compiled asset URLs and access the asset map during rendering.
• Ensure asset lookups are synchronous in server render path to avoid awaiting inside render hooks.

Description

• Adds a new hook module with ASSET_CONTEXT, useAssetMap(), useAsset() and useAssetUrl() in packages/root/src/core/hooks/useAsset.ts and exports them from core.ts.
• Wraps server render VDOM with ASSET_CONTEXT.Provider in packages/root/src/render/render.tsx to make the asset map available to components during render.
• Changes AssetMap.get signature from Promise<Asset | null> to Asset | null in packages/root/src/render/asset-map/asset-map.ts and updates implementations in BuildAssetMap and DevServerAssetMap to be synchronous, adds a find() helper and improves logging in build-asset-map.ts.
• Replaces directoryContains import usage with an inline implementation in dev-asset-map.ts and adjusts logic to correctly detect files inside rootDir and workspace roots; adds a new directoryContains() helper at the bottom of that file.

Fixes #183

Testing

• Ran the TypeScript type-check and local build, which completed successfully without type errors.
• Executed the project's unit tests, and they passed (no failing tests reported).
