v0.12.2

Fixed

• A wildcard directory in test_paths matched nothing (#136): a pattern ending in / was
  compared as a literal prefix by Project.is_test_file and joined as a literal path by the cargo
  adapter's _test_files, so crates/*/tests/ — how a workspace declares one pattern instead of
  one per crate — matched no file at all. Every test file in such a project classified as
  implementation, so a RED commit touching only tests was recorded as implementation_during_red,
  reporting the agent for writing production code it had not written; _test_files returned an
  empty list, leaving the unaccounted-files check with nothing to compare. A directory pattern is
  now matched per path segment (crates/*/tests/ covers crates/x/tests/main.rs, not
  crates/x/src/tests/main.rs), and the adapter globs it.
