Fold postfix chains into a fused RowPlan executed in plasm-runtime, replace the JSON walker, and ship .with{k: expr} with now, len, when, arith (/ and string +), and temporal day diffs.

…RowPlan
Document the new .with{col: expr} postfix in the canonical language definition
(EBNF, invariants, pitfalls) and expand plasm-row-compute with expression
semantics, chaining order, disambiguation, and RowPlan/Polars execution notes.
Add glossary entries for .with and RowPlan.
