  • Support context caching (c66245a)

    • Support explicit context caching auto creation and lifecycle management.

    Usage: App(root_agent=..., plugins=..., context_cache_config=...) * Support non-text content in static instruction (61213ce) * Support static instructions (9be9cc2) - Support static instruction that won't change, put at the beginning of the instruction. Static instruction support inline_data and file_data as contents. Dynamic instruction moved to the end of LlmRequest, increasing prefix caching matching size.
