v0.5.31

[0.5.31] - 2026-07-31

Added

• Type checking with ty as the authoritative checker: a ty.toml config, a ty dev dependency, and tests/test_type_check.py, which fails the suite on any diagnostic (and skips when ty isn't installed). The tree is at zero diagnostics, checked against Python 3.10 — the floor of the supported range — so nothing newer than 3.10 slips into the public API

Fixed

• Fixed the type errors and removed the 13 stale # type: ignore comments that ty check reported. Two were real latent crashes in example_client/client.py, which used a subscriber and its UUID without checking either for None; the example now guards once, up front, instead of suppressing the warnings
