Three small changes that together address the failure modes in #1296:
1. Add pnpm-lock.yaml and yarn.lock to SKIP_FILENAMES, mirroring the
existing package-lock.json rule. A 24K-line pnpm-lock.yaml produced
~1124 chunks in one batch and tripped onnxruntime bad_alloc on
Windows; pnpm/yarn lockfiles are no more useful to mine than npm's.
2. Skip any file that produces more than MAX_CHUNKS_PER_FILE (500)
chunks, with a clear log line. Catches the broader class — generated
CSV/JSON, build artifacts, etc. — that the named-file SKIP list will
never fully cover. The cap is conservative (500 chunks * 800 chars ≈
400 KB of source) so legitimate hand-written content still mines.
3. Print a partial-progress summary on any exception in _mine_impl, not
just KeyboardInterrupt, then re-raise. Without this, an arbitrary
exception (ONNX bad_alloc, chromadb HNSW error, OS fault) propagates
silently — the operator sees only the last progress line and assumes
the mine succeeded. The new path mirrors the KeyboardInterrupt
summary (files_processed, drawers_filed, last_file) plus the
exception type and message, then re-raises so the original traceback
surfaces and the exit code is non-zero.
Tests cover: SKIP_FILENAMES contents, the chunk-cap path returning
(0, room) with no upserts, and the new mine-aborted summary surfacing
both the partial counters and the exception class.
