feat(sidebar): improve running session state tracking

Add a running-session view to the sidebar, including header controls, running counts, empty states, and row-level processing indicators so active provider work is visible outside the current chat. Hydrate running state after refresh through a status-only /api/providers/sessions/running endpoint backed by chatRunRegistry.listRunningRuns, then sync and poll the frontend processingSessions map from AppContent without attaching to chat streams or replaying messages. Preserve fresh local processing entries during sync so newly sent messages are not cleared before the backend registry catches up, and clear completed sessions once the status endpoint no longer reports them. Thread active session state through sidebar project/session components, show rotating loaders for processing sessions, and keep the running search mode expanded and filterable. Fix optimistic local user-message dedupe so repeated prompts are only collapsed when a matching server echo appears from the same send window, preventing sent messages from disappearing until assistant completion. Add registry test coverage for listing currently running app sessions. Tests: npx eslint on changed files; npx tsc --noEmit -p tsconfig.json; npx tsc --noEmit -p server/tsconfig.json; npx tsx --tsconfig server/tsconfig.json --test server/modules/websocket/tests/chat-run-registry.test.ts.
