fix(managed-tools): wait for checksum handles before promotion

Delay managed-tool installation promotion until checksum read streams have emitted close, preventing intermittent Windows rename failures caused by open file handles.

Add a deterministic end-before-close regression test and prepare the 1.0.9 patch release across package metadata, UI version text, README, changelog, and release contracts.
