Add a complete hybrid signature implementation combining two independent signature algorithms with AND/OR verification semantics, designed for streaming pipelines. Key changes: - Add zeroecho.sdk.hybrid.signature package with core hybrid signature abstractions (HybridSignatureContext, HybridSignatureProfile, factories, predicates, and package documentation). - Introduce SignatureTrailerDataContentBuilder as a signature-specialized replacement for TagTrailerDataContentBuilder<Signature>, supporting core, single-algorithm, and hybrid signature construction. - Extend sdk.builders package documentation to reference the new signature trailer builder and newly added PQC signature builders. - Adjust TagEngineBuilder where required to support hybrid verification integration. - Update JUL configuration to accommodate hybrid signature diagnostics without leaking sensitive material. Tests and samples: - Add comprehensive JUnit 5 tests covering hybrid signatures in all supported modes, including positive and negative cases. - Add a dedicated sample demonstrating hybrid signing combined with AES encryption (StE and EtS). - Update existing signing samples to reflect the new signature trailer builder. The changes introduce a unified, extensible hybrid signature model without breaking existing core APIs or pipeline composition patterns. Signed-off-by: Leo Galambos <lg@hq.egothor.org>
