Beamscope.Chunking.ErlangChunker (Beamscope v0.1.0)

Chunks .erl/.hrl files by calling :epp in-process (no subprocess), so macros and includes are resolved exactly as the compiler would resolve them.

Ported from extract_chunks.erl plus the chunk-assembly logic in chunker.py (spec merging, oversized-chunk splitting) in the original Python-orchestrated pipeline. Parsing and the file-ownership fix (forms belonging to an -include'd header are dropped rather than chunked under the including file — see Beamscope.ErlangForms for why) are shared with the call-graph extractor.

Falls back to TextChunker's line-window only when parsing succeeds but yields zero chunks (e.g. a header with no forms) — a genuinely fatal parse failure (the file can't even be opened) yields no chunks at all, matching chunker.py exactly: its line-window fallback is gated on the extractor's exit code being 0, which a fatal failure never is.
