Multi-turn transcripts ran together visually because every user message got the same vertical rhythm regardless of position. Adds a short ─── in the border colour above every user message after the first, so each turn reads as its own block. Height estimator gains a `withSeparator` flag so virtual scrolling pre-allocates the extra two rows (rule + top margin) and avoids a jump on first measurement. While in the area: the busy-indicator duration was padded with `padStart(7)`, leaving five visible spaces between `·` and the digits (`⠋ · 2s`) — especially loud under the verb-less `unicode` style. Drop the padding entirely (`⠋ · 2s`); the model label now shifts a few columns as the duration grows, which is the right trade-off for the minimal indicator styles. The verb-padding test stays; the duration-padding test is removed alongside the function it covered.
