fix(instrumentation-py): repair Arize, AutoGen, and AWS Bedrock OTel 2.x spans

[Nightingalelyy]

Summary

• export backend-visible Arize operation status so deterministic SDK failures remain failed 500 spans with their input, output, and error
• remove duplicate/noisy AutoGen runtime spans while preserving connected agent, chat, and tool trees; retain current ToolSchema definitions, calls, complete tool-result history, and direct-agent Response output
• preserve AWS Bedrock ClientError HTTP status and current camelCase inputSchema, including complete properties and required fields
• add focused regressions and patch release intents for all three packages

Validation

• respan-instrumentation-arize: 9/9 tests

• respan-instrumentation-autogen: 18/18 tests

• respan-instrumentation-aws-bedrock: 7/7 tests

• final wheels built and clean-installed together; imports resolved from site-packages

• release-intent validation and changed-package coverage passed

• all 12 corresponding locally linked examples completed with RESPAN_EXAMPLE_RUN_ID=otel2-fix-py-group-09-20260815T212000Z

• MCP inspected all 12 trace trees and all 152 full records: counts, hierarchy, parents, content, types, model/provider, exact usage, tool identity/history, and intentional 404/500 failures passed

• Full source and paired-example diffs were audited against every applicable document under contribution/; canonical span fields, OTel attribute shapes, release-intent/version ownership, and package boundaries have no remaining package-owned violation.

External follow-ups

• AWS Bedrock emits the contribution-approved canonical llm.request.functions and completion tool-call content with the complete schema and call. Platform full detail still projects top-level tools=[] and tool_calls=[]; this PR intentionally does not add prohibited alias attributes as a package workaround.
• The corresponding example-project changes were used for live validation and are not included in this Respan repository PR.
