Commit: project: shown_path into Nikaia
Body: shown_path moves to project_tests.nika (no clash, no prefix), sync, so project.rs calls project_tests::shown_path without block_on; where fs::canonical throws it keeps the name as given, as the Rust did. Step 1 is f8614268 (fs::canonical, Path.strip_prefix, Path.clone); P3a’s, P3b’s and P4’s rows in the selfhosting plan record the std::fs prerequisite as met. lower-std fixpoint: only project_tests’ lowered file and its index line changed.
Part: #125
Tests: tests/compiler –both-settings 206 ok; it file_paths fs_ test_runner output_test program_test + guard set 51 ok; nikaia –lib project:: 10 ok; clippy clean; pre-push-check ok

Rs2nika: kept 0 of 4 lines (under 60%); costliest: path.canonicalize() catch { path.to_path_buf() } should be fs::canonical(path, fs::Root::Anywhere) catch { path.clone() } (x2), strip_prefix(..)?.display()?.to_string() catch {..} should be (path.strip_prefix(root) ?? path).display(), and sync on the signature dropped
