feat: PbjReader/PbjWriter Single PR

[ldintr]

Description:

Overview: PbjReader/PbjWriter are a leaner, buffer-reusing alternative to the existing ReadableSequentialData/WritableSequentialData read/write path used by Codec, ProtoParserTools/ProtoWriterTools, and the pbj-compiler generators. They reuse an internal ~16KB (L1-cache-sized) buffer across many parse/write calls instead of allocating per call, avoid checked-exception-based control flow by recording a sticky internal error code instead, and split hot-path operations (e.g. zigzag vs. non-zigzag varints, direct UTF-8 decode into a reusable char[]) into dedicated fast methods.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
