Purpose
PaimonCatalogperformed blocking catalog and REST I/O while holding the Python GIL. This stalls other Python threads and makes an in-process Python REST server time out after 30 seconds.Changes
Verification
test_catalog_gil.py: 1 passed in 0.56s.cargo check -p pypaimon_rustcargo fmt --all --checkgit diff --check
