Produce reconciliation.json with included_ids (sorted), excluded_pending_ids (sorted unique), duplicate_ids (sorted unique across the input), and total matching report.json.

Here is the full report.\n\n## Changed files\n- **`report.py`** — rewrote `build(source, destination)`:\n  - Reads CSV via a context-managed file handle (`newline=\"\"`, no ResourceWarnings).\n  - Amounts parsed with `Decimal` (exact cents, no binary-float summation); `f\"{total:.2f}\"` yields the total as a **two-decimal string** with zero-padding.\n  - Keeps only `status == \"posted\"`; pending rows are excluded and collected in `pending_ids`.\n  - Dedupes retransmissions: first posted occurrence per ID counts once; `duplicate_ids` covers **all** IDs (posted or pending) appearing more than once in the input.\n  - Writes `report.json` at `destination` and `reconciliation.json` adjacent to it (`dest.with_name(...)`), with all ID lists **sorted unique** and `reconciliation.total` identical to `report.total`.\n  - `python3 report.py` produces both artifacts; empty (header-only) input yields `0.00`/`0`/empty lists (dict/set/list handling makes this natural).\n- **`test_report.py`** — kept the original `Smoke.test_callable` and added acceptance tests: sample input, empty input, decimal-exact negatives + duplicates, and adjacent-artifact placement in a nested directory.\n\n## Verification evidence (`transactions.csv`: a×2 posted 0.10, b posted 0.20, c pending 10.00, d posted -0.05)\n- `PYTHONDONTWRITEBYTECODE=1 python3 report.py` produced:\n  - **`report.json`** → `{\"total\": \"0.25\", \"rows\": 3}`\n  - **`reconciliation.json`** → `{\"included_ids\": [\"a\", \"b\", \"d\"], \"excluded_pending_ids\": [\"c\"], \"duplicate_ids\": [\"a\"], \"total\": \"0.25\"}`\n- `python3 -m unittest test_report -v` with `-W error::ResourceWarning -W error::DeprecationWarning`: **5 tests, all OK**.\n- Manual cross-check of the true expected values: total = 0.10 + 0.20 + (−0.05) = **0.25**; rows = **3** (a, b, d); excluded pending = **c**; duplicate = **a** — artifacts match exactly.\n- No `__pycache__`/`*.pyc` files, no extra files; workspace contains only README, the two source files, the CSV, and the two required artifacts."
