v0.7.29

get_app_state now reuses desktop diagnostics for up to 30 seconds. Accessibility is rechecked on every cached call. Failed observations refresh readiness before returning, and failed actions and setup tools invalidate the cache. verbose: true and doctor run fresh diagnostics.

Thanks @ofek29 for the performance improvement, the KDE measurements, and the regression coverage in #305.
