- Document AssetStorage::Copied / Reference path semantics so P1-6 (asset
writer) knows that at scan time `Copied.path` is the SOURCE path and the
writer is responsible for both copying bytes AND overwriting `path`
with the destination.
- Rename the dangling-symlink test to make its scope explicit
(`dangling_symlink_pseudo_cycle_does_not_crash`); the prior name implied
a real two-step directory cycle but the targets were broken links.
- Add `two_step_directory_cycle_visited_set_breaks_loop`: builds
`a/loop -> ../b` and `b/loop -> ../a` over real directories with real
files, asserting scan terminates with a finite, deterministic asset
list — exercises the canonical-path visited-set in walker::walk_files.
