- Refactors history display using Ink's <Static> component to prevent flickering and improve performance by rendering completed items statically. - Introduces ConsolePatcher component to capture and display console.log, console.warn, and console.error output within the Ink UI, addressing native handling issues. - Introduce a new content splitting mechanism to work better for static items. Basically when content gets too long we will now split content into multiple blocks for Gemini messages to ensure that we can statically cache larger pieces of history. Fixes: - https://b.corp.google.com/issues/411450097 - https://b.corp.google.com/issues/412716309
