Add static pictures inside cells with XLSX roundtrip
Rebased onto main (conflicts with #83/#98 and main resolved by maintainer); the contributor's branch does not allow maintainer edits.

Progress docs per craftrules standards/progress-docs.md: target-app parity, gaps, roadmap with alpha gate, readiness by audience (full / mainstream / essentials) with Opus 5.5 hours, and feature, format, hardware, UI and localization parity docs.

#101/#100 added tests that name temp dirs with SystemTime::now(); #125's
disallowed-methods lint (wasm has no clock) landed alongside them.

Re-anchor loop zips objects with their measured corners instead of indexing; a sort moves
only objects anchored inside the sorted block on the other axis too (a picture at Z3 stays
put when A1:B4 is sorted). insert.picture defaults to Move but don't size (Excel's
editAs="oneCell", which the writer emits for it), and object.setAnchorMode errors on an
unknown or empty kind. Tests for each.

edit.copy and edit.cut build and return the HTML table only with
{"html": true}; the UI asks for it when the host can publish HTML, so
MCP and control-channel responses are not bloated by up to 4 MB. Tests
cover the default, html:false and html:true.

Every legacy .xls/.doc is a CFB/OLE2 file, so the signature alone isn't encryption. Walk the
compound file's directory (bounds-checked, bounded loops; raw UTF-16 scan when the structure
is unreadable) and report Encrypted only for an EncryptedPackage/EncryptionInfo stream;
other compound files are LegacyBinary with a "save as .xlsx" message. Tests build CFB bytes
in code.

shape.setText refuses edits on a protected sheet (drawing objects are
locked; there is no edit-objects allowance yet) and text longer than
32,767 characters, like a cell. The editor doesn't open on a protected
sheet and its TextEdit carries the same character limit. Tests for both.

Blank cell and row repeats that run past 16384 columns / 1048576 rows
(padding from writers with larger sheets) are clipped instead of
rejecting the file; any data or merge past the edge is still an error.
convert() builds its Cell with ..Cell::value(value) so new Cell fields
take their defaults.

smooth_run gives every segment the same number of sub-segments (cap / n, 1..100) so long
series are smoothed end to end within the point cap, and clamps the Catmull-Rom curve to
the plot box. List "smooth" in chart.addElement's params doc, drop the smooth_demo
example, and use the test sheet's own name in series refs.

Resolves the shared integration points for both formats: combined sniff,
file.open spec, file filters, MCP description, docs. open_bytes now lets
sniffed content (ODS or XLSB) win over the extension.

Clip a file chart's series block to the sheet's used range and refuse blocks over the
insert.chart cell cap, so whole-column references can't build ~1M series.
