opencrabs 0.3.47

//! Tests `FileService.get_or_create_file`'s project archiving:
//! - **Ephemeral shares** (under `~/.opencrabs/tmp/` — channel/clipboard/web
//!   downloads) are **copied** into the project files dir (the source is cleaned
//!   up, so a copy is required to keep the artifact).
//! - **Persistent local files** (drag-drop, agent-produced) are **symlinked**
//!   into the project files dir — no duplication, stays in sync with the original.
//! - **Repository code** (inside a git repo) is tracked at its real path, never
//!   archived.
