Description
Resolves #658 by adding binary and BLOB data type support across DML mutation generation and grid validation:
Binary & BLOB Literal Formatting:
_isBinaryTypeinTableMutationEnginerecognizingblob,bytea,binary,varbinary,raw,image, andbit.'\\x...'::byteaX'...'X'...'NULLsemantics for binary columns.Grid Cell Hex Validation:
GridDataTypeValidatorfor binary column types (\x...,0x...,X'...', raw hex).Testing:
test/core/database/table_mutation_engine_test.dartverifying dialect-specific binary literals.test/features/workspace/grid_data_type_validator_test.dartvalidating hex formats and rejecting invalid hex input.Closes #658
