test(p10-1c-go): code-go-ast-v1 chunker snapshot + full-suite gate

Mirrors code_python_ast_snapshot / code_ts_ast_snapshot patterns. In-memory
CanonicalDocument (no kebab-parse-code dep — boundary §6.3 respected).

verify:
- cargo test -p kebab-chunk --test code_go_ast_snapshot → 2/2
- cargo test --workspace --no-fail-fast -j 1 → 0 failures (all green)
- cargo clippy --workspace --all-targets -- -D warnings → clean
- SMOKE: chunk.ParseDoc symbol + code_lang_breakdown {"go": 1} 확인

//! Snapshot test pinning the `Vec<Chunk>` JSON for a
//! representative Go code `CanonicalDocument`.
//!
//! This is an integration test. `kebab-parse-code` is intentionally NOT
//! a dev-dep (design §6.3 / §8 boundary: AST extraction is parser-side).
//! The `CanonicalDocument` is built inline from hand-crafted `Block::Code`
//! units, which is the same pattern used in `code_rust_ast_v1.rs`'s
//! internal `code_doc` test helper.
//!
//! Set `UPDATE_SNAPSHOTS=1` to re-bake the baseline.
