## What The `InsertHeader` SMT was dropping the fractional part of literal values when the parsed schema resolved to an integral type. For example, configuring `value.literal: "2.0"` produced a header with value `2` instead of `2.0`. The `configure` method now detects this case and rewrites the schema and value to `FLOAT32`, `FLOAT64`, or `Decimal` so the original literal is preserved. The behavior change is localized to `connect/transforms/src/main/java/org/apache/kafka/connect/transforms/InsertHeader.java`. When `Values.parseString` returns an integral-typed `SchemaAndValue` and the raw configured string contains a decimal point, the literal is re-encoded using `BigDecimal`, falling back to `Decimal` for values outside the range of `float`/`double`. All other inputs keep the previous behavior. ## Why ## Testing Added `InsertHeaderTest.insertionWithFloatHeader`, which configures the SMT with the literal `"2.0"` and asserts that the resulting header carries a `FLOAT32` value of `2.0f` while preserving any pre-existing headers on the record. Existing tests continue to cover the integral and string literal paths, so non-numeric and integer literals are unchanged. --- Delete this text and replace it with a detailed description of your change.
