surface: parse text bindings with stack fallback (#13918)

Browse Source 
Text binding actions previously allocated a temporary buffer for every
escaped string. Use a 256-byte stack fallback allocator so typical
bindings avoid the transient heap allocation while larger values
continue to use the existing heap-backed behavior.
