Addresses review on #25: sheet XML omits blank rows, so error messages
now use each <row r=...> number instead of the position; the excerpt
test pins the exact row count so dropped rows fail loudly.

The February and March 2026 above-1% workbooks name the investor
column INVESTOR_TYPE (codes such as CP, ID); April onward uses
INVESTOR_CLASSIFICATION (words). Treat both as the same field; every
other column stays strict.

Since June 2026 IDX publishes the monthly "Pemegang Saham di Atas 1%"
list as an XLSX workbook on the Data Kepemilikan Saham page instead of
a PDF announcement. Add a parser for it and accept `.xlsx` in
`ownership import --file`.
- src/ownership/xlsx.rs: zip + quick-xml reader (shared strings incl.
rich text, sheet cells), exact 12-column header match so the daily
above-5% and investor-type/classification workbooks are rejected,
Excel serial dates, numeric shares, percent -> bps with float-noise
rounding. Builds KseiHoldingDraft directly and reuses the entity
normalizers, so investor types stay uppercase like the PDF path.
- Fixtures: trimmed excerpts of the real 2026-08-31 above-1% and
2026-09-23 above-5% workbooks.
- Unit + CLI tests: import, ticker, releases, above-5% rejection.
- Docs: ARCHITECTURE parser pipeline, AGENTS ownership inputs.
