The original lockfile regeneration pulled in unrelated dependency bumps
(langgraph 1.1.4→1.2.0, core 1.1.26→1.1.29) that caused TypeScript
type errors. Regenerate from main's lockfile with targeted overrides
that only change minimatch versions.
Also fix override selectors to catch minimatch@10.1.2 (in the
>=10.0.0 <10.2.1 vulnerable range) used by @typescript-eslint.

* feat(deepagents): add MemoryMiddleware for AGENTS.md support
Port of langchain-ai/deepagents#646 to TypeScript.
Adds MemoryMiddleware that loads persistent context from AGENTS.md files
following the agents.md specification. Unlike skills (which are on-demand),
memory is always loaded at agent startup and injected into the system prompt.
Changes:
- Add createMemoryMiddleware in middleware/memory.ts
- Add `memory` parameter to createDeepAgent for automatic middleware setup
- Export MemoryMiddleware from package index
- Add unit tests for memory loading and prompt injection
Usage:
const agent = createDeepAgent({
memory: [
"~/.deepagents/AGENTS.md",
"./.deepagents/AGENTS.md",
],
});

* adds config option to subagent invocations
* updates langchain and removes note about summarization middleware
* updates params to use more appropriate BaseLanguageModel class
* feat: migrate to createAgent API and middleware architecture
BREAKING CHANGE: Major refactor from custom LangGraph implementation to new langchain createAgent API
**Architecture Migration:**
- Replace createReactAgent with createAgent API from langchain package
- Migrate from custom state management to middleware-based architecture
- Remove custom DeepAgentState and model configuration in favor of built-in patterns
**Package Updates:**
- Upgrade to @langchain/anthropic@alpha, @langchain/langgraph@next
- Add langchain package as main dependency with createAgent support
- Update @langchain/core to local development version
**Code Reorganization:**
- Move tools from src/tools.ts to modular middleware pattern (src/middleware/)
- Simplify type definitions in src/types.ts with Zod schema validation
- Refactor src/subAgent.ts to use createAgent with middleware integration
- Update src/graph.ts and src/index.ts for new API patterns
**Removed Files:**
- src/state.ts: Custom state management no longer needed
- src/model.ts: Default model configuration handled by createAgent
- src/interrupt.ts: Interrupt handling integrated into middleware
**New Middleware System:**
- src/middleware/fs.ts: File system operations middleware
- src/middleware/todo.ts: Todo management middleware
- src/middleware/index.ts: Middleware exports and configuration
**Configuration:**
- Fix tsconfig.json extends path for @tsconfig/recommended
- Update examples/research/research-agent.ts for new API
- Upgrade TypeScript ESLint and other dev dependencies
This migration provides a more maintainable architecture with better separation of concerns
and aligns with the latest LangChain patterns for agent development.
