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.

Implements the two slicer commands from the parity catalog as first-class
floating objects that filter a table column.
- model: Slicer struct on Sheet (#[serde(default)]), included in
Workbook::next_object_id; slicer anchors use AnchorMode::MoveOnly.
- engine: cmd/slicer.rs with insert.slicer, table.insertSlicer, slicer.toggle
(single + multi), slicer.selectAll, slicer.clear, slicer.delete. Selection is
written as a FilterCriterion::Values into the sheet AutoFilter and applied via
the existing apply_filter. object.move / object.delete handle "slicer".
- ui-egui: slicers rendered, hit-tested, selected and dragged like charts; value
tiles toggle on click (Ctrl/Cmd = multi), funnel button clears. Ribbon buttons
under Insert > Filters and Table Design > Tools.
- tests: slicer_filters_table; the every_command_survives_empty_params fuzz
covers the new commands.
Native-only for now; .xlsx slicer-cache round-trip is a follow-up.

#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.

Fill Series by month used the previous cell's day as an overflowing DATE()
day, so Jan 31 + 1 month became Mar 3 and February was skipped. The same
overflow affected year steps from Feb 29 and the autofill month pattern.
Each item is now computed from the start date plus n months and the day is
clamped to the target month's length (Jan 31, Feb 28, Mar 31, Apr 30), so
the clamp does not compound. Leap years are handled.

Histogram, box & whisker, waterfall, funnel, treemap and sunburst charts
were written as clustered columns, and reading skipped such charts in
files made by Excel, which keeps them as cx:chartSpace (chartex) parts.
The writer now writes these kinds as chartEx parts, as Excel lays them
out: the data goes through hidden _xlchart.v1.N workbook names, each
part comes with chart style and colour parts, and the drawing frames it
in mc:AlternateContent with a text-box fallback. Fills are written out
(series in theme accents, waterfall decreases and treemap/sunburst boxes
in their own, a white chart area), so they don't depend on the style
part. The reader reads the parts back (resolving the _xlchart names,
which aren't kept as names) with data, title, axis titles, legend,
labels and colours, and follows mc:AlternateContent in drawings.
Go To (and the Name Box) with a table's name selected the whole table,
header and totals rows included. In Excel a table's name stands for its
data rows, as in formulas (=SUM(Table1) adds only the data).
Editing a table's header cell changed only the cell: the column kept its
old name, so =SUM(Table1[a]) still worked after the header read "zz",
and saving wrote the old names back into the header row, undoing the
edit on reopening. As in Excel, the column now takes the new header;
an emptied header becomes ColumnN and a repeated one gets a number
("a2"), written back into the cell, and structured references follow
the new name.
A formula whose references are only known while evaluating isn't in the
dependency graph, so when it read a spill area before the array was laid
out in the same pass, nothing evaluated it again. With the full
recalculation now laying every spill out afresh, =INDIRECT("F7") over
a spill moved by an inserted row read 0 after Calculate Now. Such
formulas are evaluated once more when a pass computed any array.
