fix(valkey): enforce max nesting depth in RESP parser to prevent stack overflow

A malicious Redis/Valkey server could send deeply nested RESP structures
(e.g., arrays nested 100,000+ levels deep) causing unbounded recursion in
readValue() and crashing the process via stack overflow (SIGSEGV). This
adds a maximum nesting depth of 64 levels, which is far beyond any
legitimate use case while preventing stack exhaustion.
