Debugging a Rust test whose code lives in a nested module (e.g. `variant_get::test::get_complex_variant`) sometimes exited immediately with "0 tests matched", When the test name itself came from tree-sitter runnable capture, which sees only the bare function identifier. So `--exact get_complex_variant` filtered out the actual test. The fix is to only append `--exact` when the name contains `::`. rust-analyzer's `experimental/runnables` produces qualified paths and keeps the #43110 disambiguation benefit, and the runnables from tree-sitter no longer break for nested modules. Closes #51810. Release Notes: - Fixed debugging Rust tests in nested modules sometimes immediately exiting with "0 tests matched".
