Detailed Description

VM opcode snippet for writing a Fun Value as JSON to a file.

Implements the OP_JSON_TO_FILE instruction. Expects a pretty-print flag, a Value to serialize, and a path. Serializes the Value via json-c and writes it to the specified file path.

Build gating: compiled only when FUN_WITH_JSON is enabled. Otherwise the opcode consumes three arguments and pushes 0 (failure).

Stack effect (with FUN_WITH_JSON):

Pops: pretty (bool/int), value (any), path (any; converted to string)
Pushes: int (1 on success, 0 on failure)

Errors and edge cases:

If the path cannot be converted to a C string or file writing fails, the opcode pushes 0.
Pretty printing selects JSON_C_TO_STRING_PRETTY; otherwise plain output.
