feat(ownership): discover above-1% XLSX on the IDX data page

IDX stopped posting the monthly above-1% list as an announcement after
the 2026-05-29 report; June/July/August are only on the Data
Kepemilikan Saham page. `ownership discover` could not see them, and
IDX's Cloudflare now rejects curl_chrome142 on that page and on the
/Media/ XLSX files.

- remote: parse the page's Nuxt payload (Description/Prospectus pairs,
  / escapes), classify above-1% XLSX as supported and above-5% /
  investor-type workbooks as unsupported, derive as_of_date from the
  Indonesian description. Keep all above-1% entries, only the newest
  of the other series. Merge with the announcement results.
- discover JSON gains `format` (xlsx|pdf) and `as_of_date`; page
  entries use the as-of date as publish_date (the page shows none).
- import --url accepts .xlsx and downloads via the XLSX validator.
- curl_impersonate: run_owned_with_fallback tries several browser
  profiles until the body validates (JSON / page payload / %PDF / PK);
  IDX_CURL_IMPERSONATE_BIN still pins one.
- Tests: page fixture parsing, date parsing, payload validation, CLI
  discover via a local page server; existing discover tests now point
  IDX_OWNERSHIP_DATA_PAGE_URL at a closed port so no test hits IDX.
- Docs: ARCHITECTURE discovery section, AGENTS ownership inputs.

@ -57,11 +57,11 @@ Ownership is local-first after bootstrap.
Preferred bootstrap/update path:
1. `idx ownership sync`
2. if no snapshot manifest is available: `idx ownership discover` then `idx ownership import --url <pdf-url>`
2. if no snapshot manifest is available: `idx ownership discover` then `idx ownership import --url <xlsx-or-pdf-url>`
3. local `--file` imports remain available for manual/fallback use
Ownership input paths:
- primary remote source: discoverable IDX `above1` holder-register PDF
- primary remote source: IDX `above1` holder register — monthly XLSX on the Data Kepemilikan Saham page (since the 2026-05-29 report), legacy PDF announcements before that; `ownership discover` checks both
- maintained snapshot path: `ownership sync`
- local file imports: IDX above-1% `.xlsx` (current format since June 2026), legacy `.pdf`, plus local archive `.zip` / `.txt`
