Pull request overview

This PR updates the Tika Pipes IPC (Smile) serialization path so inline document bytes travel efficiently as raw binary at the tuple top level (instead of being forced through ParseContext’s JSON-config round trip), and reduces wire overhead by disabling Smile’s default 7-bit binary encoding.

Changes:

• Add a dedicated inlineBytes top-level binary field to FetchEmitTuple IPC serialization/deserialization, keeping the payload out of ParseContext JSON config handling.
• Configure the IPC SmileFactory to disable ENCODE_BINARY_AS_7BIT to avoid size expansion and transcoding overhead for binary payloads.
• Add targeted unit tests and a CHANGES.txt entry covering the new wire behavior and request-body rejection of inlineBytes.
