fix flow execution: install python 3.14 in pull step, bootstrap tangled table
the worker image ships python 3.11 but pyproject.toml requires >=3.14.
add `uv python install 3.14` before `uv sync` in the pull step.
also add a dbt pre-hook to create raw_tangled_items if it doesn't exist,
so enrich can run before tangled-items has written any data.
