fix(reset): simplify compact usage and rewrite e2e test for clarity

[davidfirst]

Follow-up to #10270.

• Replace compact(compact(versionObjects).map(...)) with a clearer two-step: first compact to filter missing version objects, then compact on the mapped batchIds
• Rewrite the e2e test doc and naming to use simple A/B/C labels instead of "local snap"/"first snap"/"final snap" — makes the snap→reset→snap flow easier to follow

Pull request overview

Follow-up cleanup to the bit reset lane-history fix from #10270: it improves readability of batchId extraction during reset, and simplifies the related e2e test narrative to make the snap → reset → snap flow easier to follow.

Changes:

• Refactors batchId collection to a clearer two-step compact() flow when loading version objects during reset.
• Rewrites the lane history-diff e2e scenario naming/documentation to use “snap A/B/C” labels and updated assertions.
