v1.1.0-RC2

Features

• Harness subagents — HarnessAgent can delegate work to ephemeral child agents via agent_spawn / agent_send. Declarations come from SubagentDeclaration, workspace/subagents/*.md, built-in general-purpose, or custom factories; remote HTTP subagents are supported.
• Async subagents — Set timeout_seconds=0 to run subagent tasks in the background. Task state is persisted in the workspace and managed with task_output, task_list, and task_cancel.
• Subagent streaming — When the parent uses stream(), synchronous local subagents forward reasoning, tool, and result events into the parent Flux<Event> with EventSource metadata. Nested subagents are supported; call() keeps the previous blocking behavior.
• Tool strict mode — Tools can be configured with strict JSON-schema validation for more reliable model tool calls.
• MCP protocol versions — McpClientBuilder exposes protocolVersions for explicit MCP protocol negotiation.

Bug Fixes

• DashScope multimodal tool results — Multimodal content parts in tool results are preserved instead of being dropped.
• OpenAI rate-limit retries — Non-standard rate-limit error payloads are parsed correctly so automatic retries can trigger.
• Subagent runtime context — RuntimeContext (e.g. userId) propagates from parent tool calls into child agents for consistent isolation.
• Glob matching — File globs match both workspace-root files and nested paths (e.g. *.md, *.log.jsonl).
• Skill state APIs — Added methods to set skill states programmatically.

Other

• Improved model tool-call handling; E2E support for Qwen 3.5 series models; dependency bumps (PostgreSQL, Micronaut, OpenTelemetry semconv, zstd-jni).
