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.

The April 2026 IDX ownership PDF omits the zero-valued scrip column for
some holders, causing the parser to leave holdings_scripless/scrip as
empty strings. This broke normalize_ksei_row which called parse_id_number
on empty input.
Two-layer fix:
- Parser: pop_numeric_tail handles 2-column (missing scrip) rows by
defaulting scrip to "0"
- Normalizer: parse_id_number_or_zero backstop treats empty component
share fields as 0 while still requiring total_shares
Also includes AGENTS.md refresh, formatting cleanup (rustfmt), and
version bump to 0.2.2.

Refactor KSEI PDF parsing for the live above-1 holder-register layout, add IDX announcement discovery plus browser-impersonated PDF fetches, and update the ownership docs to mark Batch 1 complete and scope Batch 2 around above1 hardening and unsupported legacy inputs.
