fix(toolchain): pin Python floor to 3.14.6 for the frozen+slots dataclass regression (#303)
CPython 3.14.0-3.14.5 ship a regression (python/cpython#135228 + the related frozen-dataclass __setattr__ fix) where `@dataclass(frozen=True, slots=True)`'s generated __setattr__ closes over the pre-slots class, so an unknown-attribute assignment raises a spurious `TypeError: super(type, obj)` instead of FrozenInstanceError/AttributeError. AlfredOS has 36+ frozen+slots dataclasses (incl. trust-boundary types); the symptom surfaced locally because .python-version floated to a stale 3.14.4 while CI's `uv python install 3.14` already pulls 3.14.6. Pin the regression-free floor consistently: - requires-python >=3.14.6 (with explanatory comment) - .python-version 3.14.6 - docker/alfred-core.Dockerfile ARG ALFRED_PYTHON_VERSION 3.14.0 -> 3.14.6 (the in-container interpreter must satisfy the new floor; the build's `uv pip install .` otherwise fails "3.14.0 does not satisfy Python>=3.14.6") - refreshed uv.lock Verified: under 3.14.6 the repro raises FrozenInstanceError and the two previously-failing memory tests pass.
