vm: lower match() expressions natively

Walks each arm's conditions via DUP-cond, push-case, CMP_ID,
JMP_IF_TRUE chains. Arm bodies land via patched-up jump targets;
the no-arm-matched fall-through uses OP_THROW_UNHANDLED_MATCH
(or evaluates the default arm body when present).

ThrowUnhandledMatch helper is extracted so both AST and VM share
the value-formatting + Error construction (formatUnhandledMatchValue
stays an implementation detail).

Match expressions are no longer AST-delegated — IsMatchNode now
returns false unconditionally.
