Pull request overview

Refactors protocol-specific decoding to move decoder wiring out of reader.Reader and into internal/context.Context, while making byte-order explicit at call sites and standardizing reader error values.

Changes:

• Introduces context.Decoders (parameter parser + reliable header parameter counter) and threads it through context.NewContext / parser constructors.
• Simplifies reader.NewReader (no options) and updates numeric read APIs to take an explicit binary.ByteOrder.
• Updates v16/v18 parameter parsing and multiple command/session parsing call sites + tests to match the new context/reader APIs.
