fix: switch to Responses API and remove duplicate assistant message#33

…ponses API
With the Responses API, when the outer loop manually pushed
step.response.messages back into context.messages and re-called streamText,
the provider had to re-convert {role:'tool'} history to function_call_output
format across separate API calls — an unreliable round-trip that broke the
second tool trigger.
Setting maxSteps: MAX_STEPS delegates all tool-call cycles within a single
user turn to the SDK, which manages the function_call / function_call_output
pairing internally and consistently. The outer loop now only handles
context compaction, retries, and per-user-turn iteration.

The Responses API defaults store=true, which uploads conversation data for model improvement. Set store:false unconditionally so data is not retained server-side. Reasoning effort is still applied when configured. https://claude.ai/code/session_01FLbdEJ2hYu4mwmkLvFiNbx

Responses API instead of Chat Completions
since onResponse already accumulates step.response.messages; the
duplicate caused consecutive assistant messages which broke multi-turn
conversations in the Responses API
