Tab switches into a long session paid for everything that was already paid for
the last time the user was on that session. Specifically the per-message height
and metric maps were cleared on every switch, so the new commit could only feed
estimated heights into buildVirtualTranscriptWindow and then chase them with
ResizeObserver callbacks. The first commit also ran getBranchableMessageTargets
and getCompletedTurnTargets — two extra O(N) walks over the messages array —
synchronously, and scrollToBottom('auto') was called inside the switch's
useLayoutEffect, which (on JSDOM and depending on layout state) added a
scrollHeight read to that critical path.
Introduces virtualHeightCache, a small module-level LRU keyed by sessionId that
holds the height and metric maps. MessageList now reads the prior maps on
switch instead of clearing them, so revisiting a session uses real measured
heights from the previous visit and skips the estimate→measure-correction
cascade. tabStore.closeTab calls dropSession so closed tabs don't leak.
The two O(N) branch / completed-turn computations now read from
useDeferredValue(messages), so they run as a low-priority follow-up render
after the first paint instead of blocking the switch commit. The switch's
useLayoutEffect now writes the bottom sentinel directly instead of calling
scrollToBottom, keeping the layout-read path out of the synchronous switch.
Tested: 731/731 desktop vitest suites pass, including 5 new virtualHeightCache
