An icon-set rule without stored thresholds (every rule made by
home.conditionalFormat, and the sales sample) was written as an empty
<iconSet>, which CT_IconSet forbids (cfvo minOccurs 2); openpyxl drops it.
The writer now always emits one cfvo per icon: the stored thresholds when
there is one per icon, the lower bound prepended when it is missing, else
Excel's defaults (percent 0/33/67, 0/25/50/75, 0/20/40/60/80).
Evaluation read the thresholds as one fewer than the icons, but files
carry one per icon (the first is the lower bound), so thresholds read from
a file were ignored. Both now share icon_count and default_icon_thresholds
in gridcraft-model; icon_count is clamped to 3..=5 so a set name like
"0Foo" can't underflow k - 1.

Excel decides duplicates by what a cell displays, not the value stored:
the same date shown as 3/8/2006 and as Mar 8, 2006 is two values, while
1.01 and 1.02 both shown as 1.0 are duplicates. Remove Duplicates
compared stored values, so it did the opposite in both cases.
With Case sensitive checked, Sort compared text by code point, so every
uppercase word came before every lowercase one (A, B, a, b). Excel
compares ignoring case first and only then puts lowercase before
uppercase: a, A, b, B.
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.

#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.
