Philipinho 5ebab5cd9e fix(base): make cell-extractor pg functions genuinely parallel-safe ...

The plpgsql + EXCEPTION versions of base_cell_numeric,
base_cell_timestamptz, and base_cell_bool were labeled PARALLEL SAFE
but EXCEPTION blocks require subtransactions, which Postgres cannot
start in a parallel worker. Any parallel scan that invoked them
crashed with 'cannot start subtransactions during a parallel
operation' — notably DuckDB's postgres extension on large base COPY
reads.

Rewrite each as a pure SQL function using jsonb_typeof + regex
validation for the 'coerce-or-null' semantics. No plpgsql, no
subtransactions, genuinely parallel-safe. Signatures unchanged so
existing call sites (loader, expression indexes, engine predicates)
are untouched.
