refactor(registry): introduce Repository and InstallerExecutor traits

Sets up DI scaffolding for in-process installer E2E tests, mirroring how
Composer's PHPUnit suite swaps Packagist (FactoryMock) and the install
manager (InstallationManagerMock) without touching the network or filesystem.

Additions:
- Repository trait + RepositorySet (Composer's RepositoryInterface analog),
  with PackagistRepository, InlinePackageRepository, VcsRepository impls.
- InstallerExecutor trait (Composer's InstallationManager analog) with
  FilesystemExecutor extracted from install_from_lock.

install_from_lock now delegates per-package install/uninstall verbs to
FilesystemExecutor; console output orchestration stays in the caller so
existing --EXPECT-OUTPUT-shape assertions remain comparable. No behavior
change - all 136 enabled installer fixtures still pass.

Also tightens the installer_fixture\! ignore form to a single token
(installer_fixture\!(name, ignore)) for readability.
