Subject: feat(test): add HttpDownloaderMock, IOStub, and Config stub helpers

stubs. Wired into util/repository/downloader/command test targets.

+//! Configurable Config stub, equivalent to PHPUnit's
+//! `getMockBuilder(Config::class)` where `get('x')` is stubbed via
+//! `->method('get')->willReturn(y)`.
+//!
+//! `Config` is a concrete (non-trait) struct, so rather than mocking it we build a
+//! real `Config` and seed the requested keys through `Config::merge`, which is how
+//! `get('key')` actually resolves its value. This keeps the stub faithful to the
+//! real resolution logic instead of intercepting `get`.
