pip: bump lmdb from 1.6.2 to 2.2.1

[dependabot]

Bumps lmdb from 1.6.2 to 2.2.1.

Changelog

Sourced from lmdb's changelog.

2026-06-03 2.2.1 #################

Improvements

• lmdb.aio async wrapper methods (on AsyncEnvironment, AsyncTransaction, and AsyncCursor) are now real class attributes rather than synthesized by __getattr__, making them visible to dir(), inspect.signature(), help(), IPython, and stubtest. Non-callable attributes still proxy through. (#460, contributed by jorenham)

• Added type stubs for the lmdb.aio module. (#455, contributed by jorenham)

Fixes

• Fix a segmentation fault on Linux/aarch64 when an Environment is closed from a different thread than the one holding an active write transaction. Environment.close() now waits for the owning thread to release the write transaction before unmapping the lock file. (#465, reported by sdvillal)

• Reject adversarial on-disk values that could overflow size arithmetic or cause implementation-defined narrowing of mv_size when reading crafted databases. (#462, #463)

• Fix crashes on out-of-memory conditions in the CPython extension's error paths. (#453)

• Fix and modernize the type stubs, including __all__ exports and the Cursor.iter* parameter defaults in __init__.pyi. (#454, #457, #459, contributed by jorenham)

Other

• Remove remaining Python 2 compatibility code. (#456, contributed by jorenham)

• Run the test suite natively on Linux/aarch64 in CI; previously aarch64 wheels were built but never tested. (#465)

2026-03-29 2.2.0 #################

New features
