Research direction
The issue names no files or tests. Start by comparing source-generator byte[] binding with runtime reflection-based binding, then trace handling for Base64 strings, array values, and existing arrays. Done means array values append correctly, Base64 binding remains supported, and invalid values throw when BindingOption.ErrorOnUnknownConfiguration is enabled.

Description
The configuration source generator currently supports binding a byte[] only from Base64-encoded strings. This issue aims to enhance byte array binding to align with the behavior of runtime reflection-based binding. The improvements should include:
- Support for array values in configuration: Enable binding from array-style configuration values (e.g., JSON entries like
byteArray: [1, 2, 3, 4]) in addition to Base64 strings. - Preserve and extend existing arrays: When binding to an already-initialized (non-null) byte array, the configuration values should be appended to the existing array rather than replacing it—consistent with the behavior of other array types.
- Error handling for invalid values: If invalid configuration values are encountered, an exception should be thrown when the
BindingOption.ErrorOnUnknownConfigurationflag is enabled.
