Parse XML tool calls from text responses

[chubes4]

Summary

• Parse XML-style <function_calls>/ tool calls when a provider returns them as text instead of native FunctionCall DTOs.
• Preserve native tool-call extraction priority and use the XML fallback only when no native calls are present.
• Add sandbox/pipeline smoke coverage proving XML tool calls execute and return to the provider for a final answer.

Tests

• php tests/agent-conversation-runner-request-smoke.php

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
• Used for: Investigated WP Codebox sandbox transcripts showing text-form tool calls, drafted the fallback parser and smoke coverage, and ran local verification.
