v0.2.7 — TUI Crash Fix

Fix

• Fixed terminal crash when using /models, /provider:add, or /settings commands
• Root cause: bold: true is not a valid style property in @OpenTui <text> elements, causing the terminal renderer to crash
• Also disabled chat keyboard handler when provider modals are open to prevent input conflicts
