Problem

A web request can fail with:

Circular dependency detected: Quantum\Http\Request -> Quantum\Http\Request

Root path:

• Request bootstrap parses uploaded files
• UploadedFile::__construct() eagerly resolves fs() and uploads config
• That path reaches Setup and request() while Request is still resolving
• DI correctly detects recursion and throws

Scope

Apply a minimal fix in UploadedFile:

• keep constructor side-effect free
• lazily resolve filesystem/config only when needed for file operations

Acceptance Criteria

• No circular dependency on request bootstrap when files are present
• Existing upload behavior remains unchanged
• Relevant unit tests pass (UploadedFile, Request, request file trait, web adapter flow)

Notes

This ticket is intentionally narrow and does not include broader upload architecture refactoring.
