"Failed to load session" loop after context compaction — app unrecoverable without fresh session

Description

When a session runs out of context and gets continued into a new conversation (via context compaction/summary), attempting to reopen the app repeatedly shows "Failed to load session" with a "Back to landing page" button. The app does not recover — quitting and relaunching hits the same error. This happened 4 times consecutively.

Steps to Reproduce

1. Have a long-running Claude Code session that hits context limits
2. Session gets compacted and continued into a new conversation
3. Quit the app (or it crashes/freezes)
4. Relaunch — app tries to reload the old session ID
5. "Failed to load session" error appears
6. Quitting and relaunching does not help — same error every time

Expected Behavior

App should fall back to the landing page cleanly if a session is unloadable, not loop on a dead reference.

Actual Behavior

Stuck in a reload loop on a dead session ID. Only escape is starting a completely fresh session.
