Surgical edits to ~/.consciousness/config.json5 that preserve comments,
whitespace, trailing commas, and unquoted identifier keys on round-trip.
Uses json-five's rt::parser module — a real JSON5 parser with AST
mutation + faithful serialization back. set_scalar(section, key, literal)
locates or creates the target, replaces the value; set_learn_threshold
is a convenience for the common F-screen use case.
