* feat: add json_object scalar function
Builds a JSONB object from interleaved (key, value, ...) arguments, like
MySQL's JSON_OBJECT. Values are written into the binary directly, so
JSON-hostile characters (quotes, backslashes, control characters) need no
text-level escaping. Keys must be non-NULL strings; values may be strings,
numbers, booleans, or NULL (JSON null).

* fix: build entity-graph JSON objects with json_object
The derivation assembled entity_id_attrs and descriptive by concatenating a
JSON text and parsing it, escaping only backslash and double quote in runtime
values. A label containing a control character (e.g. a newline) produced
unparseable text and failed the whole semantic_entities scan instead of one
attribute. json_object assembles the JSONB binary directly from the value
columns, so no text escaping is involved; NULL-to-'' stays at the call site.

* fix: json_object() returns an empty object; narrow values to integers and floats
MySQL's JSON_OBJECT allows an empty pair list, so the signature accepts zero
arguments and the row count falls back to number_rows. Decimals stay rejected
instead of casting to Float64: JSONB numbers (i64/u64/f64) cannot represent
them exactly and a silent precision loss is worse than an explicit cast.

* chore: document key-to-string conversion and align test naming
Keys follow MySQL JSON_OBJECT: any castable type is converted to string.
Rustdoc and the cast-failure message now say so, with a numeric-key test.
Test names take the module-conventional test_ prefix.
