DTree

:desc
Dynamic tree/container type used throughout UCE for structured data.

`DTree` can hold a `String`, `f64`, `bool`, pointer, or a nested map of child `DTree` values.

Use `t["key"]` to access or create child entries. Use `push()` / `pop()` when treating it like an array-like container with numeric string keys.

Common uses include:
`json_decode()` / `json_encode()`
`context.var`
`context.call`
`call_file()` return values

Useful methods include:
`to_string()`
`to_json()`
`get_type_name()`
`get_by_path()`
`set_bool()`
`remove()`
`clear()`
`each()`
