alex 949baf0804 docs: Add spec for undefined-expression failure behaviour
Adds docs/product/undefined-expression-failure.md, the product spec and
acceptance criteria for gating node failure on an expression resolving to
undefined behind a per-node setting (default off).

Documents verified prior art in the expression stack: interpolated chunks
already coerce undefined to empty string in shared tournament codegen, so
the criteria scope the check to the whole resolved parameter value and
leave expression resolution untouched.
