github.com/francoispqt/gojay v1.2.13: Decoder

# gojay Decoder Usage Notes

## Goal
Verify `github.com/francoispqt/gojay.Decoder` in `pkg:golang/github.com/francoispqt/gojay@v1.2.13`.

## Observed Behavior & Contract Proof
1. **Object Decoding (`NewDecoder` & `DecodeObject`)**:
   - Types implementing `gojay.UnmarshalerJSONObject` implement `UnmarshalJSONObject(dec *gojay.Decoder, key string) error` and `NKeys() int`.
   - The decoder parses JSON keys and populates fields using methods such as `dec.AddInt`, `dec.AddString`, `dec.AddBool`, `dec.AddFloat64`, and `dec.AddSliceString`.
2. **Array Decoding & Pooling (`BorrowDecoder`, `DecodeArray`, `Release`)**:
   - `gojay.BorrowDecoder(io.Reader)` retrieves a pooled `Decoder` instance to decode slices implementing `gojay.UnmarshalerJSONArray`.
   - `dec.Release()` returns the decoder back to the pool for reuse.
3. **Scalar Decoding**:
   - Primitive scalar values can be decoded directly using `dec.DecodeInt`, `dec.DecodeString`, `dec.DecodeBool`, `dec.DecodeFloat64`.
4. **Error Handling**:
   - Passing malformed JSON to `DecodeObject` returns a decoding error.

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify github.com/francoispqt/gojay.Decoder in pkg:golang/github.com/francoispqt/gojay@v1.2.13
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:golang/github.com/francoispqt/gojay@v1.2.13
Demonstrate these symbols/APIs:
  - github.com/francoispqt/gojay.Decoder

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
