fix: add chat hitl for agent framework

[cristipufu]

Pull request overview

This pull request adds Human-in-the-Loop (HITL) tool approval support to the UiPath Agent Framework, enabling agents to request human approval before executing sensitive tools. The implementation integrates with the UiPath Chat runtime to suspend execution, emit approval requests, and resume after receiving user responses.

Changes:

• Implemented HITL tool approval flow with @requires_approval decorator for marking sensitive tools
• Added comprehensive end-to-end tests for HITL workflows and breakpoint scenarios across all sample topologies
• Updated dependency versions to agent-framework-core 1.0.0rc1 and agent-framework-orchestrations 1.0.0b260219
• Enhanced runtime with conversion logic between agent framework Content objects and UiPath CAS approval format
• Improved checkpoint SQL query determinism and enum comparison logic
