fix(openai, anthropic): cast empty tool args to object (laravel#419)

* Fix empty tool args in Anthropic and OpenAI maps

When mapAssistantMessage() rebuilds tool_use blocks from stored ToolCalls,
empty arguments were serialized as [] instead of {}, which both APIs reject.
Apply the same empty-only coercion used in the other gateways and add tests
for empty and non-empty args in both mappers.

* Update AgentTest.php

Bedrock correct default model IDs (laravel#460)

Bedrock provider (laravel#270)

* [0.x] Add AWS Bedrock provider

Adds full support for AWS Bedrock as an AI provider with text generation,
embeddings, image generation, and speech transcription capabilities.

Features:
- Text generation with 50+ models (Claude, Titan, Llama, Mistral)
- Tool/function calling with multi-turn conversation support
- Streaming text generation via Bedrock's converseStream API
- Image generation (Nova Canvas, Titan Image, Stability AI)
- Speech transcription (Nova Sonic) with diarization
- Embeddings (Titan Embed, Cohere Embed)
- Support for IAM credentials, bearer tokens, and default credential chain
- Comprehensive exception handling and error recovery
- Rate limiting via HandlesRateLimiting trait

Closes laravel#39

* Fix structured output for Bedrock via forced tool-use

When a HasStructuredOutput schema is provided, the previous implementation
simply called json_decode() on the model's text response. Since Bedrock
models respond conversationally by default (not as raw JSON), this always
returned an empty array.

Fix: when a schema is present, inject a synthetic 'structured_output' tool
whose inputSchema is built from the agent's schema definition, then set
toolChoice to force the model to call that tool. The tool's input block is
already parsed JSON by the AWS SDK, so we json_encode() it back for the
existing json_decode() path downstream.

This matches the industry-standard approach (LangChain, LlamaIndex, etc.)
for reliable structured output from Claude on Bedrock.
