Function ResolveFileInputStrategy

ResolveFileInputStrategy(
    mimeType: string,
    fileSizeBytes: number,
    capabilities: FileCapabilities,
    forceNativeFileInput: boolean,
    currentFileCount: number,
): FileInputStrategy
Determines whether to use native file input or artifact tools for a given file, based on LLM driver capabilities and an optional prompt-level override.

Resolution order:
1. Prompt-level forceNativeFileInput override (if non-null, returns immediately)
2. Driver capabilities null-check (null = no file support)
3. MIME type, size, and count constraints checked against driver capabilities
4. Falls back to artifact tools when any constraint is violated
Parameters
- mimeType: string
- fileSizeBytes: number
- capabilities: FileCapabilities
- forceNativeFileInput: boolean
- currentFileCount: number
Returns FileInputStrategy
