Docs: sync the progress docs with issues closed on 2026-10-10 (#1064)

The parity and roadmap docs were last refreshed before a batch of fixes
merged, so they still described closed issues as open problems.

- #774 (encrypted output rejected by Acrobat, fixed by #836): gap 1
  removed from gaps.md; its remaining interop-suite work moved to gap 12.
  Gap numbers are kept so existing "gap N" references stay valid.
- #756 (Windows printing, #847): Printers row, Print area and roadmap
  rank 1 now name web printing as the remaining gap.
- #740 column select (#765), #759 1:1 touchpad scrolling (#868),
  #810 Shift-Cmd-G (#835), #825 (#822).
- #844 multi-object move (#907): marked partial, same page only.
- #799, #800, #807, #809, #811, #815-#819, #821 (incl. the #816 panic):
  gap 6 and the area tables list them as fixed.

Scores, readiness percentages and the stage are not re-judged; only the
rank-0 estimate drops by gap 1's 8-15 h (40-70 -> 32-55).

 ## The gaps
 
-### 1. Encrypted files we write don't open in Acrobat
-
-- **Missing:** interoperable encryption output. A document protected with a password in PdfCraft
-  opens in PdfCraft, SumatraPDF, PDF24 and LibreOffice, but Adobe Reader, Acrobat and PDF-XChange
-  report it as damaged.
-- **Evidence:** [#774](https://github.com/storytold/pdfcraft/issues/774) (2026-10-10, confirmed by a
-  second user). Our encryption tests round-trip through our own reader and `qpdf --check`, which
-  is more lenient than Acrobat.
-- **Impact:** blocking. Passwords are the most common reason to touch security; a file a recipient
-  can't open is data loss in practice. Partial sub-case of the convert-and-share gate row (unencrypted sharing works), so not an alpha blocker; the first beta item.
-- **Fix:** find the divergence (likely `/Encrypt` dictionary or R6 `/Perms`/`/OE`/`/UE` details, or
-  a string/stream encrypted that must not be), then add an interop suite that opens every kind of
-  output we write in other readers (pdf.js, MuPDF and Poppler as oracle processes; Acrobat by hand
-  on the owner's Mac).
-- **Estimate:** 8–15 h. **Doc:** [file-format-parity.md](file-format-parity.md).
