bump dependencies

[akhatre]

Note

Medium Risk
Primarily dependency/version bumps, but updates to langgraph/langgraph-prebuilt and orjson (including a Python version floor change in the lock) could introduce subtle runtime/compatibility regressions.

Overview
Bumps the SDK version to 0.1.33 and updates the langgraph dependency requirement to >=1.0.10 (lockfile resolves to 1.1.3, with langgraph-prebuilt to 1.0.8).

Regenerates poetry.lock with Poetry 2.3.1 and updates locked transitive deps (notably orjson to 3.11.7, plus minor metadata/extras adjustments), resulting in a new lock content-hash.
