fix(agent-sessions): centre the transcript, open a tool call from anywhere on its header - #959

The transcript column pinned to the left edge of the content area: the clock gutter and the 900px prose column sat flush left, so a wide window was all empty space to their right. Cap the list at the width a typical row actually wants and centre it.
📝 WalkthroughWalkthroughThe transcript now aggregates usage at turn level, displays token and cost totals in turn headers, centers content within 1052px, and uses full-width tool-header toggles. Per-call usage and reasoning-token details are removed or suppressed. ChangesTranscript usage and presentation

The card's header was two targets: the left half selected the span, which in the transcript only drew a ring around a card the reader was already looking at, and a 12px chevron at the far right was the only thing that opened the payloads. The whole header now toggles the pair, and the selection highlight is gone.

changed the title
… header Every model call in the transcript printed its own token split and cost, so a turn of twenty calls repeated the same two figures twenty times. The calls now print model, ttft and stop reason only, and the chapter header carries the turn's summed usage — counted by the same deepest-reporter rule the session header uses, so the turns still add up to the total above them. Timestamps are untouched.

Avoid a leading metadata separator.
A prompt row can contain captured input without model, TTFT, or finish metadata. With { usage: false }, callMetaLine can return an empty string, so the current render produces · {serviceName}.
Join only non-empty metadata parts.
Proposed fix
- {callMetaLine(row.span, { usage: false })} · {row.span.serviceName}
+ {[callMetaLine(row.span, { usage: false }), row.span.serviceName]
+ .filter(Boolean)
+ .join(" · ")}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Two fixes to the agent session transcript.
Centred column. The transcript pinned to the left edge of the content area — the 88px clock gutter and the 900px prose column sat flush left, leaving a wide window as empty space to their right. Caps the list at 1052px (gutter + two nesting lanes + the body's padding + the prose column — what a typical row actually wants) and centres it with
mx-auto;w-fullkeeps narrow viewports unchanged. The wrapper is the one outside the measured rows, so the virtualizer's offsets and scroll margin are untouched.One target per tool card. The header was two: the left half selected the span — which in the transcript only drew a ring around the card the reader was already looking at — and a 12px chevron at the far right was the only thing that opened the arguments and result. The whole header now toggles the payloads, and the selection highlight is dropped.
?span=still scrolls the transcript to the row it names; the other blocks' selection is unchanged.Verified against the fixture at
/lab/agent-session?view=transcript: centred at 1800px, unchanged at 900px, a click on the call id and a click on the tool name each open and close the pair, and a failed call'serror.typepill still sits right of the header.apps/websession-detail tests pass (81).Summary by CodeRabbit
