fix(langchain): fix response action for HITL ( #33131 )
...
Multiple improvements to HITL flow:
* On a `response` type resume, we should still append the tool call to
the last AIMessage (otherwise we have a ToolResult without a
corresponding ToolCall)
* When all interrupts have `response` types (so there's no pending tool
calls), we should jump back to the first node (instead of end) as we
enforced in the previous `post_model_hook_router`
* Added comments to `model_to_tools` router so clarify all of the
potential exit conditions
Additionally:
* Lockfile update to use latest LG alpha release
* Added test for `jump_to` behaving ephemerally, this was fixed in LG
but surfaced as a bug w/ `jump_to`.
* Bump version to v1.0.0a10 to prep for alpha release

test(core): enhance stringify_value test coverage for nested structures ( #33099 )
...
## Summary
Adds test coverage for the `stringify_value` utility function to handle
complex nested data structures that weren't previously tested.
## Changes
- Added `test_stringify_value_nested_structures()` to `test_strings.py`
- Tests nested dictionaries within lists
- Tests mixed-type lists with various data types
- Verifies proper stringification of complex nested structures
## Why This Matters
- Fills a gap in test coverage for edge cases
- Ensures `stringify_value` handles complex data structures correctly
- Improves confidence in string utility functions used throughout the
codebase
- Low risk addition that strengthens existing test suite
## Testing
```bash
uv run --group test pytest libs/core/tests/unit_tests/utils/test_strings.py::test_stringify_value_nested_structures -v
```
This test addition follows the project's testing patterns and adds
meaningful coverage without introducing any breaking changes.

<p>This update, introduces automatic caching when a valid
<code>packageManager</code> field is present in your
<code>package.json</code>. This aims to improve workflow performance and
make dependency management more seamless.
To disable this automatic caching, set <code>package-manager-cache:
false</code></p>
