Pi Agent Platform v1.43.5

Image previews and office attachments. Sent images show as pictures, spreadsheets and slide decks attach directly, and screenshot-heavy tasks no longer stop on Studio's request size limit.

Added

• Attached and sent images show as pictures in the conversation and open full size; the composer chip shows a thumbnail.
• Attach .xlsx, .xlsm, .pptx, .odt, .ods, .odp and .rtf: sheets come through as tab-separated rows and slides in order with their notes, without a converter.

Fixed

• A company task with many screenshots no longer fails with request_too_large: each request resends only the newest images within 2 MiB; older ones become a note.
• A streamed answer from a turn with tools starts a new paragraph for each model message instead of running sentences together.
