crates/ui-egui/src/grid.rs: kept object_menu (2084) and error_check_tag (2095), both fns and both calls.
crates/ui-egui/src/i18n/de.rs, pt.rs: union of the entries.
docs/ui-parity.md: one status line naming both changes, both history rows.
Numbers stored as text are skipped by SUM and friends, and GridCraft gave
no hint. Like Excel's background error checking, a constant whose text
would be a number if typed now gets a green triangle in its top-left
corner; with such a cell active, a warning button beside it opens a menu
naming the problem with Convert to Number, which converts every flagged
cell in the selection as one undo step.
- core: `parse::number_stored_as_text` (signs, thousands separators,
currency, percent, exponent, one parenthesised negative). Dates, times
and fractions kept as text are not flagged, as in Excel.
- engine: `cmd::formulas::number_stored_as_text(cell)` (constants only,
not formula results) and `formulas.convertToNumber {range?}`, which
keeps each cell's format.
- ui: the triangle in the grid and the warning button with its menu;
pt-BR and German strings.

along: =1+1+... with 4,096 operands (8,192 characters, exactly Excel's
limit, which Excel accepts and calculates) overflowed the stack when
entered, because the derived Clone of Expr recursed once per operand
down the chain's left spine. Saving hit the same in the XLSX writer.
- Expr: Clone, PartialEq, walk and map follow the left spine in a loop
and recurse only into right operands and real nesting.
- XLSX: _xlpm. prefixing and the implicit-intersection scan follow the
spine too. The scan's depth limit of 64 wrote any chain of more than
about 64 operands as a dynamic-array formula; such sums are plain
formulas again (ranges in the chain still get array evaluation).
- Evaluate Formula borrows sub-expressions instead of cloning each
operator's subtree (quadratic memory on a long chain).
- Spanish formula entry and display no longer refuse chains of more
than 256 operands; the left spine does not count as nesting.
Tests run on a 1 MiB stack (the Windows main thread) with Excel's
observed results: formula (clone/eq/walk/map/adjust at 4,096), calc
(401 and 4,096 operands, -, *, /, ^, &, %, comparisons, 1,500 refs),
xlsx (long chains written as scalar formulas), engine (cell.set, fill,
copy/paste, insert rows/columns, undo/redo, Evaluate Formula, XLSX save
and reopen), Spanish entry. Each fails without the fix.

iter_range walks the sparse store's bands for the area's row range
only, so a chain of N formulas no longer rescans every stored cell of
the sheet per area.

Bound the all-level walk to the sheet sparse cell store instead of
iterating every position of each precedent area: formulas late in a
wide area are no longer skipped, blank positions are never selected,
and only formula cells extend the frontier. Adds a regression test
(=SUM(A1:Z1) with a formula at Z1) and silences two clippy lints in
the same function.

Adds formulas.selectPrecedents / formulas.selectDependents engine commands
and binds them to Ctrl+[ and Ctrl+] (Ctrl+Shift walks every level), matching
Excel's shortcut parity. Direct-level traces keep whole precedent ranges;
cross-sheet precedents jump to the owning sheet; an empty trace leaves the
selection untouched with an actionable message.

A formula read with `cm` (Excel's XLDAPR dynamic-array record in
xl/metadata.xml) now carries `Formula::dynamic`, and the writer keeps the
`cm` and the metadata part for it even when the formula returns one value
and the export shape analysis would not need array evaluation. Before, such
formulas were saved as legacy formulas, so Excel recalculated some of them
with implicit intersection (SUMPRODUCT(IFERROR(range/range,0)) changed
value), and workbooks whose every dynamic formula was scalar lost
xl/metadata.xml altogether.
The mark survives moves, row and column insertion or deletion, sheet and
name renames and LAMBDA call-case fixes; retyping a formula drops it and
the writer decides from the formula's shape, as before. It is serialized
only when set, so saved documents without it are unchanged.

`formulas.evaluate` (behind `gridcraft-cli eval` and MCP's `evaluate_formula`) turned any
formula that didn't parse into #NAME?, so `=SUM(1;2)` looked like an unknown function. It now
parses the way `cell.set` does (missing closing parentheses are added) and returns the same
errors: "There's a problem with this formula: expected `,` or `)`, found Semicolon", or the
wrong-argument-count message. An unknown function still evaluates to #NAME?, as in Excel.
A name whose references have no $ was evaluated as if they were
absolute. In Excel such references are relative: defined from B2,
=Sheet1!A2 means "the cell to the left", and the file stores it
relative to A1 (Sheet1!XFD1, wrapping around the sheet's edge).
Name formulas with relative references are now moved by the using
cell's offset from A1, wrapping at the edges, and formulas.defineName
takes relative references as relative to the active cell, as Excel's
Name Manager does, and stores them relative to A1.
Evaluator special form returning the range (or array) without its blank
outer rows and columns; trim codes 0-3 as documented; written as
_xlfn.TRIMRANGE. The trim-reference operators are not parsed yet.

dialogs::show put the Name Manager back into app.dialog after its body
had opened the New Name dialog, so New… did nothing. A dialog opened from
another one now takes over and the opener waits behind it (back), coming
back when the child closes; Go To still hands over to Go To Special.
The Name Manager gets Excel's New…/Edit…/Delete buttons over a selectable
list. formulas.defineName takes oldName/oldScope to edit a name in place;
a renamed name is renamed in cell formulas and other names' definitions.

cell_param returned None for any cell argument it could not parse, so every
command that falls back to the selection (cell.set, view.freezePanes,
formulas.trace*, insert.* and others) silently used the active cell instead:
set_cell with cell "ZZZZ0" wrote A1 and reported success. It also dropped a
sheet prefix, so "Other!B2" was applied to the active sheet.
cell_param now returns Result<Option<CellRef>>. An absent or null value is still
None, so the selection fallback is unchanged; an unparsable or non-string value
is an error; a sheet prefix naming a sheet other than the one the command works
on is an error.
cell_param_on is for the commands that resolve their own sheet (cell.get, links,
comments, notes, checkboxes, chart placement, paste): they accept a prefix naming
that sheet. cell.set resolves its own target sheet and still writes to another
existing sheet.
formulas.createFromSelection ignored bottom and right, and replaced any
workbook name with the same label without asking. Bottom-row and
right-column labels now name the cells above and to their left. An
existing name is kept and listed in the result's skipped, unless
replace is set (Excel asks; a command doesn't open dialogs).
Moving a sheet left its sheet-level names on whatever sheet took its
index, and copying it shifted nothing and copied no names. Moving now
re-indexes name scopes, and a copy gets copies of the sheet's names,
referring to the copy, as in Excel.
Deleting a sheet left names that referred to it pointing at nothing;
they now become #REF!. formulas.deleteName honours scope, and the Name
Manager's Delete passes it.
