* fix: add default value to grep tool glob schema for strict mode compatibility
The grep tool's `glob` field was defined with `.optional().nullable()` but
without `.default()`, causing it to be excluded from the JSON schema
`required` array. This violates OpenAI's strict mode requirement that all
properties must be listed in `required`.
Fixes#401
* Fix grep tool glob schema for strict mode
Added a default value to the grep tool glob schema to ensure compatibility with strict mode.

* feat(sdk): evict large HumanMessages to filesystem
Port of python PR #2183 to JS. Adds a beforeAgent hook to the
FilesystemMiddleware that checks the most recent message. If it is a
HumanMessage whose text content exceeds toolTokenLimitBeforeEvict, the
full content is written to the backend and the message is replaced with
a truncated preview pointing to the file.
Changes:
- Add TOO_LARGE_HUMAN_MSG template for evicted human messages
- Add extractTextFromMessage() to extract text from any message type
- Add buildEvictedHumanContent() to preserve non-text blocks (images)
- Add beforeAgent hook to createFilesystemMiddleware
- Add comprehensive tests for HumanMessage eviction

* refactor: align with final Python PR - tag-based eviction architecture
Rework the HumanMessage eviction to match the final shipped Python PR:
Architecture change:
- beforeAgent: writes large content to backend and TAGS the message
with lc_evicted_to in additional_kwargs (preserving original content
in state for checkpoint persistence)
- wrapModelCall: truncates all tagged messages before sending to model
(model sees preview, state keeps full content)
Key differences from initial port:
- Separate humanMessageTokenLimitBeforeEvict option (default: 50000)
- Original content preserved in state (not replaced)
- Messages tagged with lc_evicted_to for multi-turn truncation
- Path changed from /large_messages/ to /conversation_history/
- Added buildTruncatedHumanMessage helper for model-view truncation
- wrapModelCall now handles truncation of all tagged messages
Tests updated:
- beforeAgent tests verify tagging behavior (original content preserved)
- New wrapModelCall test suite for truncation of tagged messages
- Test for skip already-tagged messages
- Test for mixed tagged/untagged message lists
- Test for non-text block preservation during truncation

* fix: update beforeAgent to use resolveBackend after main merge
The merge from main replaced getBackend/StateAndStore with
resolveBackend/BackendRuntime. Update the beforeAgent hook to use the
new API.

* fix(deepagents): reorder middleware so prompt caching and memory run last
Move anthropicPromptCachingMiddleware and memoryMiddleware after all static
