The event tab's per-event usage view already renders every usageMetadata field, but the "Usage Summary for Session" totals aggregated only prompt, candidates, and total tokens. Cached-content (cache-read) and thoughts (reasoning) tokens were invisible at the session level, even though they matter for cost tracking. Sum cachedContentTokenCount and thoughtsTokenCount across the session's events and add "Total Cached Content Tokens" and "Total Thoughts Tokens" rows to the session summary. Each row renders only when its total is greater than zero, so sessions without caching or reasoning are unchanged.

What
Adds session-level totals for cached-content (cache-read) and thoughts (reasoning) tokens to the Event tab's "Usage Summary for Session".
Why
The per-event usage view already renders every
usageMetadatafield, but the session-level rollup only summed prompt, candidates, and total tokens. Cache-read and reasoning tokens are billed differently and are useful for cost-at-a-glance, so they belong in the session totals too.Changes
event-tab.component.ts— extend thesessionUsageMetadatacomputed to also sumcachedContentTokenCountandthoughtsTokenCount.event-tab.component.html— add "Total Cached Content Tokens" and "Total Thoughts Tokens" rows, each shown only when its total is> 0, so sessions without caching/reasoning look unchanged.Testing
npm run buildpasses.
