The same session can appear in two render contexts at once — most
visibly under "Recent" and under its project's root group. Expansion
state was keyed by bare session id, so toggling the chevron in one
context flipped it in the other; the user clicked one row and a
duplicate elsewhere expanded/collapsed in sync.
Switch the expansion set to composite keys of the form
`<renderContext>:<active|archived>:<sessionId>`. SessionNodeItem
already computes this exact shape for its menu instance key
(menuInstanceKey); reuse it as expansionKey so the two render-time
instances of one session keep independent expand state. Updated:
- isExpanded reads `expandedParents.has(expansionKey)`.
- Chevron click / Enter / Space pass `expansionKey` to toggleParent
instead of session.id.
- The memo-equality check compares the same composite key on both
sides so it correctly re-renders when only one context's state
changes.
- toggleParent's parameter is renamed `expansionKey` to reflect the
new shape; the implementation is unchanged.
- The auto-expand-parent-on-subagent-navigation effect doesn't know
which context the user will look at the parent in, so it fans the
parentID out to all four (project|recent) × (active|archived)
combinations.
Storage is bumped to `oc.sessions.expandedParents.v2`. Existing v1
data (bare session ids) is one-shot migrated by fanning each id
across all four contexts and rewritten under the v2 key; the v1 key
is then removed so a downgrade-then-reupgrade doesn't re-migrate.
