fix(multi-cli): populate multiCliPlan sessions in liteTaskDataStore

Fix task click handlers not working in multi-CLI planning detail page.

Root cause: liteTaskDataStore was not being populated with multiCliPlan
sessions during initialization, so task click handlers couldn't access
session data using currentSessionDetailKey.

Changes:
- navigation.js: Add code to populate multiCliPlan sessions in liteTaskDataStore
- notifications.js: Add code to populate multiCliPlan sessions when data refreshes

Now when task detail page loads, liteTaskDataStore contains the correct key
'multi-cli-${sessionId}' matching currentSessionDetailKey, allowing task
click handlers to find session data and open detail drawer.

Verified: Task clicks now properly open detail panel for all 7 tasks.
