Preserve explicit stream values in binary cursor bindings

Explicit cursor parameters already support stream resources as LOB bindings. Reversing a binary attribute cast must not send those raw bytes through the readable UUID or ULID encoder, which rejects resource values.

Normalize streams through BinaryParameter::fromStream before invoking the caster. Keep non-binary attributes unchanged and preserve native conversion errors for malformed readable values. Extend the existing explicit-cursor regression while retaining binary-wrapper, encoded-cursor and source-alias coverage without duplicate execution.

The regression reproduces the resource TypeError before the correction. The complete binary and cursor integration suites pass on SQLite, PostgreSQL, MySQL and MariaDB; formatting and complete static analysis also pass.
