test(p10-1c-jk): code-java-ast-v1 + code-kotlin-ast-v1 chunker snapshots

//! Snapshot test pinning the `Vec<Chunk>` JSON for a
//! representative Java 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.
