Glyph 1.1.7: Chat and local models work again in the installed app

A short, unglamorous release. Chat was failing with "The connection dropped before I could answer" on every model, and local models would not load at all in the installed build. Both work again. Fixes Fixed chat failing with "The connection dropped before I could answer" on every model, local and cloud. Streaming replies now work again in the installed app. Local models load correctly again in the installed app. Saved API keys are stored in the system keychain again instead of repeatedly failing. The model download window now opens centred instead of off to the right. Starting GlyphNet without a password now shows a hint instead of reporting an error, and the hint clears once the password is long enough. Glyph 1.1.7 is available from fortaify.com, and installed copies update themselves.
