papyri.error_collector

Error bookkeeping for papyri gen.

ErrorCollector is a context manager that wraps each per-qualname generation step. It distinguishes two buckets of failures:

• expected — listed under [global.expected_errors] in the package's gen TOML; these don't fail the build.

• unexpected — anything else; logged with a traceback and re-raised when early_error is set.

A third state, fail_unseen_error, raises UnseenError when an expected error never actually fired (so the allow-list stays trimmed).
