Release 0.8.140

Prepares the stable release from the current main tip. The publish workflow creates the release tag and publishes packages after this PR merges.

• feat(render): report encoding and assembling progress #5137: Show progress while encoding frames and assembling the output file.
• fix(check): stop false sweep_static and text-overlap alarms on compositions that are fine #5147: Recognize paint and media changes during composition checks, and avoid false text-overlap alarms by measuring visible glyphs.
• fix(engine): auto worker count stays within the heap budget #5149: Keep automatic capture workers within the render process memory budget. Explicit worker requests remain unchanged.
• fix(engine): motion blur works over video by holding each video frame across samples #5150: Enable motion blur over video. Hold the footage at each output frame while sampling moving graphics around it.
• fix(cli): load telemetry without the core and engine barrels, and stop the history test racing #5153: Start CLI commands with fewer loaded modules and make history lock tests wait for the actual lock attempt.
