Add host normalization and ResolveServerKey to match equivalent endpoints (localhost/127.0.0.1, bracketed IPv6, etc.) so reconnects reuse existing server profiles. Harden profile storage: sanitize save-folder components, use Documents fallback via _dupenv_s when needed, log write/open failures, and fix Windows build issues from unsafe getenv usage. Make session launch resilient to missing or rotated exit saves by accepting Exitsave... names, refreshing to the newest exit save, and falling back to first-time flow from the main menu (instead of hard-failing). Update session launch to prefer resolved profile keys, touch/bind profiles appropriately, and improve related load error handling. Also add a simple Creation Kit quest script (CO_Vault109StartQuestScript) and update changelog/docs to document these changes.
Introduce server validation and a session launch flow with persistent server profiles.
- Add ConnectAndValidateServer to Networking to validate handshake/timeouts and return human-friendly errors; avoid auto-connecting in transform send path and remove unconditional local connect on startup.
- Add ServerProfileStore (header + implementation) to persist server->saveFile bindings under Documents/My Games/.../CommonwealthOnline/server-profiles.json with thread-safe load/save, lookup, touch and bind operations.
- Add SessionLaunch (header + implementation) to handle launching validated sessions, first-time join flow (auto coc to SanctuaryExt, character creation menus, save binding), F4SE message handling and periodic Update processing.
- Update ServerBrowserBridge to parse/validate ports, use ConnectAndValidateServer, display joinLoading UI events, schedule validated session launch on the game task thread, and centralize join success/failure handling.
- Wire SessionLaunch into main.cpp (update loop and F4SE message hook).
- Improve direct-connect UI in app.js with client-side validation, port parsing, and handling of joinLoading events.
These changes provide better connection validation, user feedback during joins, and automatic handling for first-time server joins with persistence of associated saves.
