Little Arms Launcher v0.12.8

New Features:

• Invalid session handling: dedicated prompt when the server/session is no longer valid, so you can acknowledge what happened instead of a silent or confusing logout.

Fixes:

• Startup tolerates failed session creation (e.g. network issues) more gracefully instead of leaving the launcher in a broken state.
• DLC symlinks: logic fixed when a symlink exists but its target does not, avoiding wrong assumptions during updates.
