chore(checkpoint-conformance): remove test_list_global_search, bump to 0.0.2 (#7444)

## Summary
- Remove `test_list_global_search` from the conformance test suite. This
test required cross-thread `alist(None, filter=...)` support that not
all checkpointer implementations provide.
- Remove the corresponding entry from `ALL_LIST_TESTS`.
- Bump `langgraph-checkpoint-conformance` version from 0.0.1 to 0.0.2.

## Test plan
- [x] Verify `test_list_global_search` function definition is fully
removed
- [x] Verify `test_list_global_search` is removed from `ALL_LIST_TESTS`
- [x] Verify version bumped to 0.0.2 in pyproject.toml
