bump(deps-dev): bump google-adk from 1.31.0 to 2.0.0

[dependabot]

Bumps google-adk from 1.31.0 to 2.0.0.

Release notes

Sourced from google-adk's releases.

v2.0.0

2.0.0 (2026-05-19)

ADK 2.0 General Availability

This release introduces v2.0.0 General Availability (GA) of the Google Agent Development Kit (ADK), establishing production-grade foundations for multi-agent workflows and advanced dynamic agent collaboration.

Core Architecture Highlights

Multi-Agent Workflow Engine

• Flexible Execution Graphs: Establishes a model-agnostic engine for orchestrating non-linear, conditional, and cyclical agent execution patterns.
• Intelligent Task Delegation: Introduces modular workflow abstractions enabling parallel sub-agent workers, nested hierarchical team structures, and resilient dynamic scheduling across complex task execution steps.

Dynamic Agent Collaboration

• Native Inter-Agent Routing: Provides seamless orchestration for inter-agent messaging, control state handoffs, and context variable propagation across collaborative multi-agent flows.

v2.0.0b1

2.0.0-beta.1 (2026-04-21)

Highlights

• Transition to Beta: Updated documentation to reflect the project's move to Beta phase (84e792fd).
• Security Fix: Resolved a potential RCE vulnerability related to nested YAML configurations (2b54c4ac).
• Documentation & Style: Modularized the ADK style guide and added new topics (9bb21795).
• Workflow Orchestration Core:
  • Added the full Workflow(BaseNode) graph orchestration implementation (c25d86f1).
  • Introduced NodeRunner for per-node execution isolation (0b3e7043).
  • Added DefaultNodeScheduler for standalone node resume via ctx.run_node() (a68e70d5).
• Agent Execution Models:
  • Added explicit ReAct loop nodes to replace legacy single agent flows (94453619).
  • Supported BaseNode as the root in both the Runner and the CLI (91b56b9a, 1c2a81bb).
• State & Resumption:
  • Added Human-in-the-loop (HITL) resume via event reconstruction (ca327329).
  • Added lazy scan deduplication and resume for dynamic nodes (d600b195).
  • Supported flushing state/artifact deltas onto yielded events (00153088).
• Performance:
  • Optimized execution by bypassing the Mesh for leaf single-turn LlmAgent instances (d864917f).

v2.0.0a3

Features

• Workflow Orchestration: Added Workflow(BaseNode) graph orchestration implementation, support for lazy scan deduplication and resume for dynamic nodes, partial resume for nested workflows, and state/artifact delta bundling onto yielded events.
• CLI and Web UI: Added support for Workflow graph visualization in web UI, improved graph readability with distinct icons and shapes, and active node rendering in event graph.
• Documentation: Added reference documentation for development (skills like adk-style, adk-git, and observability architecture).
