Bug: Upgrading langchain to ^1.0.0 conflicts with langchain-experimental ^0.3.4, which requires an older langchain-community version. This will cause dependency resolution to fail.
Severity: CRITICAL

Suggested Fix

To resolve the dependency conflict, update langchain-experimental in pyproject.toml to a version compatible with langchain ^1.0.0, likely ^0.4.x or higher. After updating, run poetry lock and poetry install to verify the dependencies can be resolved successfully.

Location: pyproject.toml#L58

Potential issue: The update to `langchain="^1.0.0"` in `pyproject.toml` introduces a
dependency conflict. The project also depends on `langchain-experimental="^0.3.4"`,
which has a strict requirement for `langchain-community` to be a version less than
`0.4.0`. However, `langchain 1.0.0` requires a newer, incompatible version of
`langchain-community`. This conflict will prevent the project's dependencies from being
installed, causing the build or deployment process to fail immediately.
