Pair Flow v0.4.5

Added

• Pair Flow: Choose Model picks the provider (OpenAI, Anthropic, Gemini, OpenRouter, Ollama) and then a model: suggested models with the default marked, the models your key can use, or Other model… for any id. Set API Key now ends with the same model step.
• Sessions are no longer canceled when you start a new story or switch away. Each one stays saved, and the start screen lists open sessions under Pick up where you left off with Resume and Discard. Recent sessions has a Resume button too.

Fixed

• Provider errors show the provider's own message instead of raw JSON. A wrong model id (for example gtp 5 mini) suggests the closest valid one and shows a Choose model button; Try again then uses the new model in the same session.
• Long error text and long ids wrap inside the panel instead of overflowing it.
