Support Anthropic 1M context window for Amazon Bedrock provider

증상

The context1m: true option currently only works with the direct Anthropic API provider (provider === "anthropic"). When using Amazon Bedrock via the Converse API, the 1M context window beta (context-1m-2025-08-07) requires injecting additionalModelRequestFields with anthropic_beta, which OpenClaw does not currently support.

원인

Input exceeded the model’s maximum context length, causing truncation or a refusal to process the full request. 카테고리: context-window.

해결법

Manual patch of @mariozechner/pi-ai/dist/providers/amazon-bedrock.js:

Strip [1m] suffix from modelId before sending to Bedrock
When model ID contains [1m], inject additionalModelRequestFields: { anthropic_beta: ["context-1m-2025-08-07"] } into the Converse API call

This patch must be reapplied after every npm update.
