Module json 

A JSON writer, because the alternative is 30 crates.

Mira serializes exactly one shape — query results — and it does so from hand-written code that already knows the shape statically. serde_json would buy derive macros for structs that do not exist here (results are built column-wise straight out of Arrow arrays, never as a tree of Rust values) at the cost of serde + serde_json + syn + quote + proc-macro2 and a compile-time hit on every build. This is the whole feature in a hundred lines.

The nesting API takes a closure per container so brackets cannot be unbalanced and commas cannot be missed: there is no end_object to forget.
