add wire format parser and serializer for booleans , strings and arrays

[Devansh-18155]

Previously, the MATLAB only supported flat numeric arrays because concore_read.m was using regex to strip all brackets and parsing only floats with sscanf. This caused booleans and strings to be silently dropped and flattened nested lists . also concore_write.m was using num2str which broke when trying to send cell arrays or strings.

Added a parser (concore_literal_eval.m) and serializer (concore_literal_serialize.m) that properly handle booleans, strings with escapes, nested lists, tuples, and numbers in MATLAB native types (cell arrays, logicals).

Fixes #574
