v0.4.8

Added

• gemini-2.5-pro as a second Google Gemini menu option. Aegis previously single-pointed Gemini support on gemini-3.1-pro-preview. Preview endpoints carry no SLA guarantee from Google — when the preview model is throttled at Google's serving layer (which can happen unpredictably), Gemini becomes unavailable in Aegis even though other variants on the same OAuth credentials work. The new GA-stable gemini-2.5-pro entry gives users a reliable fallback path; the existing 3.1 Pro Preview remains selectable for bleeding-edge use.

Changed

• Mid-session /model recovery now mirrors initial model selection on validate failures. Previously, /model selecting a provider whose validate() returned a transport/capacity-class error (e.g. HTTP 503) printed a generic "Couldn't verify... Staying on the current model" message and silently bailed back to the conversation. Now both flows route through a shared validation function and surface the same four-option recovery menu (Retry validation / Pick a different model / Save anyway / Abort) with the same auth-vs-transport classifier wording. The user can recover from a transient capacity issue mid-session without exiting and restarting.
• Google menu labels sharpened to communicate preview status: Google Gemini 3.1 → Google Gemini 3.1 Pro Preview; the new GA entry shows as Google Gemini 2.5 Pro.
