Widening the partialjson constraint in #6123 invalidated poetry.lock's
content-hash, so a bare `poetry install` in sdk-python fails with
"pyproject.toml changed significantly since poetry.lock was last generated".
CI never saw it because test_unit-python-sdk.yml runs `poetry lock` first, and
publishing is unaffected because `poetry build` ignores the lock — but local
dev is blocked until someone relocks. Refreshed with Poetry 2.1.3 (the lock's
own generator) so the diff stays limited to the hash, and moved partialjson to
1.1.0 so CI exercises the version a fresh install now resolves. ag-ui-langgraph
is deliberately left at 0.0.42: a from-scratch resolve pulls 0.0.43, which
fails four intercepted-tool-call tests on a missing `emit_raw_events`.
The parse path had no coverage at all — disabling JSONParser.parse outright
left all 225 tests passing, because every partialjson failure mode degrades to
"no predicted state was emitted" behind the bare `except` in predict_state().
These tests pin the guarantees the `>=0.0.8,<2.0.0` range must keep, and are
version-agnostic about intermediate frames, which legitimately differ (1.1.0
preserves trailing whitespace mid-string where 0.0.8 dropped it).
