Spreadsheets put an HTML table next to the tab-separated text; Excel
(x:num) and LibreOffice Calc (sdval) record each cell's number there.
Paste now reads the HTML flavour (new paste_html host service, arboard on
desktop) and edit.paste takes an optional html param: a field that would
paste as text becomes the recorded number when the HTML cell shows the
same text, with an inferred format ("Rp"#,##0.00) that renders it back
identically.

A plain drag copies a lone number and extends every other series; Ctrl+drag
(Cmd on macOS) now does the opposite, as in Excel: a lone number counts up
by 1, and numbers, dates, lists and `Item 1`-style text are copied.
edit.autoFill gains mode "alternate" for this.

Turning the filter on with a multi-cell selection used the selection as the
filter range. With only the header row selected, the filter had no data rows:
the dropdown list was empty and filtering hid nothing. A one-row selection
now extends down over the current region below it. An explicit `range`
parameter is still taken as given.
The filter menu gets a search box, as asked for in the issue. It narrows
the value list; Select All then reads "(Select All Search Results)" and
covers only the matches, and Apply keeps only the checked matches. The box
takes focus when the menu opens, so typing no longer lands in the active
cell.

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.
home.conditionalFormat took any operator it didn't know as "greater",
so a Cell Value rule given Excel's own names (lessThan, greaterThan,
lessThanOrEqual, greaterThanOrEqual, as in the file format and VBA)
silently became "greater than". Those names are now accepted, as data
validation already does, and anything else is an error.
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.

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.

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.
