5.9.1
(fix): Respect the customer’s smart-casing flag from generators.yml when computing
Python identifiers from compressed v66 IR strings. Previously the v1 Python
generator’s _smart_snake and v2’s PYTHON_CASE_CONVERTER were both hardcoded
with smartCasing: true, causing names produced by the generator to diverge
from the IR’s pre-computed snake_case values when the customer set
smart-casing: false. This manifested as wire-test method calls and Pydantic
field aliases that did not exist on the generated client (e.g. test calling
set_fcmv_1_provider() while the client method was named set_fcmv1provider).
_smart_snake and the v2 caseConverter now read casingsConfig.smartCasing
from the IR and switch between smart-casing semantics (default) and plain
lodash semantics (smart-casing: false). No effect for customers who use
the default; fixes generation for customers like auth0 that opt out.
