TabHelm 0.30.0

Added

• Skip waiting in recordings (Experimental flag, with how much of each wait to keep): still stretches — loading, the agent thinking — are cut from the video and marked "⏩ N s of waiting skipped". A 45 s task typically becomes a ~10 s video; step lists still seek to the right moment.

Fixed

• Recordings could not be seeked and did not preview in Slack. MediaRecorder writes a streaming (fragmented) file with a keyframe only every ~20 s. Videos are now encoded with WebCodecs into a regular H.264 MP4 with its index at the start (fast start) and a keyframe every 2 s; the encoder also keeps working while the side panel is hidden. (Vendored mp4-muxer, MIT.)
• Back after the agent opened another page could land on about:blank — Chrome skips pages left without a click — and the agent was then stuck ("Chrome does not allow extensions to control about:blank"). Navigation now works from any page, and Back returns to the page the agent came from.
• Tests no longer read or overwrite the user's ~/.tabhelm/state.json (the e2e test keeps the host's backup in its own profile).
• End-to-end tests no longer fetch the live news feed (a banner appearing mid-test shifted the Settings layout under a click).
