Jinjing cb21824bd9 Optimize hidden chat subscriptions and tab projections (#36047)
* perf(tab-bar): patch tab agent projections per changed tab instead of rescanning every layout

The shared TabBar agent projection rebuilt agent types and tab-wide chat
fallback safety from every terminal layout (~2.5k at the captured scale) and
every status row whenever either map's identity changed. Status pings that
keep each pane's agent type now reuse the cached projection, and layout edits
re-resolve only the added, replaced or removed tabs. Key reorders, agent-type
changes and added/removed status rows still take the full projection.

* perf(ai-vault): keep rank and owner-only updates from re-collecting every agent conversation

The AI Vault title subscription ran two full agent-conversation collections
(every terminal tab, retained, sleeping and live record) whenever any owner
input changed identity, including worktree rank/unread patches and unrelated
settings writes. Compare worktree rows through the existing owner-rows token
so rank-only patches skip the check, and reuse the conversation workspace set
while the agent/tab maps it reads are unchanged, so owner-only updates compare
only those workspaces' hosts. Real host moves still schedule a title rescan.

* perf(native-chat): project only changed sessions on structured status feed ticks

Each host status feed tick re-captured every structured chat member on that
host (hundreds at the captured scale), resolving each tab's owner about three
times plus companion pin checks, even though a status event names one
session. Members whose feed facts (summary, observation, failure, sleep and
launch directory) and tab are unchanged since their last consumed capture are
now skipped, and tab owners are cached until an owner input changes, with
worktree rows compared through the rank-insensitive owner-rows token.

An input is marked consumed only after projection returns normally, so a
throwing store commit still retries on the next emission. The bridge remains
the only writer of slept-at and launch-directory pins, so skipping unchanged
members does not drop a needed re-assertion.

* perf(native-chat): skip the per-render scroll-margin offset walk in hidden chats

The transcript window re-read its scroll margin through an offsetTop walk in
a dependency-free layout effect, so every render of every retained chat forced
a synchronous layout read, including display:none panes where the walk cannot
produce a margin. The read now runs only while the pane is visible; becoming
visible re-renders and measures, and mount/resize measurements are unchanged.

* perf(native-chat): stop rank and catalog writes from rerendering every mounted chat

useNativeChatImageRuntimeContext shallow-subscribed each chat root to
worktree rows, runtime environments, SSH state and other owner maps, then
resolved the context in render. A worktree rank patch or a host catalog
timestamp refresh replaced one of those maps and re-rendered the whole
NativeChatStructuredSession of every mounted chat, hidden ones included (57 of
57 probes per write in the subscription benchmark). The selector now resolves
the context itself and keeps the previous identity while the result is
shallow-equal, so chats re-render only when their route or path changes.

* Optimize hidden chat subscriptions and release closed tab state

* Share layout diffs across tab bar projections

* Strengthen tab agent projection fuzz coverage

- Use a stable PRNG that exercises the full operation space
- Assert tab, agent, layout, and operation coverage
