Provide a buffered stream implementation for Ruby, independent of the underlying IO.

Please see the project documentation for more details.

Please see the project releases for all releases.

• Rename done? to finished? for clarity and consistency.

• Fix EOF behavior to match Ruby IO semantics: read() returns empty string "" at EOF while read(size) returns nil at EOF.

• Add support for buffer parameter in read, read_exactly, and read_partial methods to allow reading into a provided buffer.

• On Ruby v3.3+, use IO#write directly instead of IO#write_nonblock, for better performance.
• Introduce support for Readable#discard_until method to discard data until a specific pattern is found.

• Split stream functionality into separate Readable and Writable modules for better modularity and composition.
• Remove unused timeout shim functionality.
• 100% documentation coverage.

• Fix compatibility with Ruby v3.3.0 - v3.3.6 where broken @io.close could hang.

• Improve compatibility of gets implementation to better match Ruby's IO#gets behavior.

• Add support for read_until(limit:) parameter to limit the amount of data read.
• Minor documentation improvements.

• Add comprehensive tests for buffered? method on SSLSocket.
• Ensure TLS connections have correct buffering behavior.
• Improve test suite organization and readability.

• Add external test suite for better integration testing.
• Update dependencies and improve code style with RuboCop.

• async-io — Where this implementation originally came from.
