teknium1 771f1b7f21 fix(desktop): route live-turn and history actions by the current session, not a stale closure
Redirect/steer, regenerate, restore-checkpoint, edit-message, and
change-cwd read `activeSessionId || activeSessionIdRef.current`, which
prefers the closure-captured prop whenever it is non-null and only falls
back to the ref once the prop is null.

That precedence is backwards. The actions bag is a stable ref that
wiring.tsx mutates in place (Object.assign), and the pane surfaces are
memoized on that stable ref, so a surface does not re-render when the
active session changes and keeps whichever closure was current when it
last rendered. `activeSessionIdRef` is the authority: it is mirrored
during render in use-session-state-cache, and submit.ts /
use-session-actions pin it imperatively mid-flight without touching the
source prop. The prop is stale by design. `cancelRun` in the same file
already reads the ref exclusively and documents exactly this hazard.

User-visible effect after switching chats: a typed correction was
delivered into the previously focused conversation's live turn (the
"session suddenly working on another chat's task" report), and rewinds
truncated the wrong session's transcript — real data loss, since a
truncating resubmit deletes history after the target ordinal. Nothing
crosses over in stored state, which is why a DB/transcript audit of the
affected session comes back clean.

Also fixes the same defect in `changeSessionCwd`, where a stale target
re-anchored another conversation's workspace, pointing that agent's
terminal/file tools at the wrong project. The now-unused
`activeSessionId` option is dropped from useCwdActions rather than left
as a footgun for the next caller.

Not changed, verified not affected: model-edit-submenu reads the runtime
id via `useStore` (live subscription, re-renders on change), and
use-composer-actions guards on `attachedSessionId === activeSessionId`,
so a stale value there only skips a detach instead of writing
cross-session.

Tests: 4 regression cases pin each action to the current session when
the prop and the ref disagree. Verified to fail against the pre-fix code
(all four reported the stale `rt-abc123` instead of the current
session), including a scripted revert of all four sites.
