* Sonar: explicit imports, fn paths for closures, extract helpers for cognitive complexity
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
* Fix imports
* Fix serde imports
* Fix engine imports
* Fix clippy gate and a type error from the explicit-import change
Remove the unused imports the review flagged (cf.rs, pivot.rs, tables.rs, cmd/sheet.rs) so clippy -D warnings passes, and point the backstage parent-folder lookup at Path::to_str, which the fn-path rewrite had broken.

* Apply rustfmt to the explicit-import cleanup so the fmt gate passes
* Share the per-directory font path expansion in theme.rs
The candidate font lists repeated the same loop over the Linux font
directories in every role. A single helper expands them in the same order,
so the lookup order is unchanged and the duplicated blocks go away.

* Read the Windows fonts folder in one place in theme.rs
Every script-font list repeated the same WINDIR lookup. A single helper
returns the same path, so the duplicated lines go away without changing
which font files are tried.

* Build the light and dark UI palettes from one table in theme.rs
Tokens::light() and Tokens::dark() listed the same 40 colour fields in the
same order, so every change had to be made twice. A single palette
constructor takes the mode and picks each colour's value, so each field is
written once and both modes keep their exact colours.

* Share the Noto CJK font list between the CJK script lists in theme.rs
The Japanese, Simplified and Korean lists each repeated the same loop over
the Linux CJK directories with a different locale file name. One helper
builds that loop, and each list keeps its own face index, so the lookup
order is unchanged.

* Share Linux Noto directory list across Thai and Hebrew font lookups
Removes the duplicated directory arrays flagged by SonarCloud new-code duplication.
* Reuse in_dirs for Thai and Hebrew Noto font candidates
Removes the remaining duplicated per-directory loops flagged by SonarCloud.
* Share one font-list builder for the Thai and Hebrew faces
The two per-script functions repeated the same Windows, macOS, Linux and
variable-font setup. A single script_fonts helper now builds both lists,
keeping the candidate order unchanged, which clears the Sonar duplication gate.

Sweep findings from the ac8da7d4 security scan (storytold-gridcraft-agent-
findings.json), remaining on main at 72c1d57d:
- finding 14 (crates/calc/src/eval.rs:988): every lambda invocation now
spends one charge against a per-cell work budget (16M — one per cell of
the largest array a reference may expand to), so a hostile, deeply
nested LAMBDA/LET formula stops at the bound a legitimately wide one
could reach instead of growing exponentially with nesting. Exhaustion
is #CALC!, like the existing depth cap. Metered at `call_lambda_values`
so every path into a body is counted (direct application, MAP/REDUCE/
SCAN/BYROW/BYCOL/MAKEARRAY, D-function criteria); the criteria
sub-evaluator hands its spend back to the parent.
- finding 16 (crates/functions/src/criteria.rs:313): `match_from` takes a
step budget (1<<26: an honest match against Excel's 32,767-char cell
ceiling costs a few hundred thousand steps), and `wildcard_find` drops
the leading star run (a no-op for a prefix match) so the first literal
anchor skips straight to its occurrences; all suffix attempts share one
budget. Star churn degrades to no-match instead of quadratic work.
Unit tests: mock-host exhaustion/under-budget for lambda applications
(eval::fuel_tests), nested REDUCE under budget in full recalc, wildcard
behaviour unchanged.

- PMT: take rate / m first so (pv + fv) / m can't overflow for a tiny rate (PMT(1e-300,10,1e12)).
- Keytips probe: an empty params object keys like no params.
- Number Stored as Text check reads the same accounting parentheses as typed entry.
- Lookups: a NaN number falls back to the general comparison instead of comparing equal.

Typed entry, VALUE and arithmetic now read $(1,234), $ (5) and (5)% as
negative numbers, as Excel 365 does. Parentheses no longer nest: (-5),
((5)), $5% and dates in parentheses stay text. This changes main's
((100)) from 100 to text; the no-recursion guard from #2180 is kept and
its test now asserts the new result.
PMT computed (1 + rate)^nper with powf, which rounds 1 + rate first and
drops the low bits of a small rate. Over 400 synthetic probes that left
PMT up to about 1000 ULPs from Excel (59 bit-exact); the ln_1p/exp_m1 form
is within 4 ULPs (244 bit-exact). A loan schedule guarded by
IF(p - SUM(principal) > 0, ...) turns on those bits: in 3000 synthetic
schedules main disagreed with Excel on the number of live periods in 1382,
the fix in 823.
Also follows Excel at the edges: a rate of -1 or less is #NUM!, a huge
nper gives -pv*rate instead of #NUM!, a tiny rate no longer collapses, and
a small negative rate keeps its payment. IPMT, PPMT, CUMIPMT and CUMPRINC
pick this up through pmt_calc. FV and PV are unchanged: Excel's own FV/PV
sit further from the exact value than the current powf form does.
The tests allow the one-ULP libm difference between platforms.
- #2369: its test joins the single ui-egui integration-test binary (tests/it), as main now builds them.
- #2367: a cell set to empty text is a blank entry and doesn't grow the AutoFilter (CodeRabbit).
- #2387: MOD's range check also covers the sign-corrected remainder (CodeRabbit).

From the local CodeRabbit review: the result was bounded per match, but
one match's expansion was built whole first, so a replacement repeating
$0 10,000 times over a 32,767-character match allocated about 330 MB
before the check. The replacement is now split into pieces as regex's
Captures::expand reads it (template_expands_like_regex checks they agree)
and appended piece by piece within the bound: 327 MB peak became 7 MB
(regexreplace_bounds_its_result).

- Text coercion: digits too many for a finite number are not a number,
and a fraction must come out finite, so "1 <400 digits>/<400 digits>"
(inf/inf) no longer coerces to NaN (test overlong_digits_stay_text).
- VLOOKUP/HLOOKUP and the D-functions' field index refuse NaN, which
passed their "< 1" checks and became index 0, then underflowed
(test nan_index_is_a_value_error; hostile_inputs_never_panic now also
passes NaN and infinity to every function).
- REGEXREPLACE replaces match by match and gives up once the result can
only be too long, instead of building every replacement first: the
32,767 x 32,767 worst case went from 1.05 GB peak to 7 MB
(test regexreplace_bounds_its_result).
#2165 (MAP's size check) is already fixed on main by the broadcast cap
(836b2698, #2182), whose test covers MAP.
Also adds my contributors/people.toml entry.

LINEST, LOGEST, TREND and GROWTH built k x k normal-equation matrices
(plus two copies in sym_inverse, O(k^3)) with k taken straight from the
known_xs shape, so one formula could allocate gigabytes and abort on open.
More than 255 predictors is now #VALUE!, and more than 1e9 rows x k^2
multiply-adds is #NUM!, both checked before any allocation.

Sheet names starting with '.' or reading as R1C1 (R, C, RC, R1C1...) were saved
unquoted, so Excel could not open the file; PivotTable sources and ADDRESS left
cell-like names (A1) bare. The quoting rule, unquoting and sheet splitting now
live once in gridcraft_core::addr and replace the copies in the formula printer,
pivot, ADDRESS, chart, xlsx, Solver, Go To and the Name Box (which now reads ''
as ').

weekend_mask rejected the all-weekend string outright for both
NETWORKDAYS.INTL and WORKDAY.INTL, but Microsoft documents them as
differing: NETWORKDAYS.INTL "Using 1111111 will always return 0",
WORKDAY.INTL "1111111 is an invalid string". The crate already
implements that split — workday_core's per_week == 0 guard — which was
unreachable dead code while the extra clause stood. Drop the clause:
NETWORKDAYS.INTL counts zero workdays as documented and WORKDAY.INTL
errors through the guard it already has.
The existing test asserted the old behaviour and is updated.
Regression: working_days — on main the NETWORKDAYS.INTL assertion fails
(#VALUE! where Excel returns 0); with the clause dropped it passes and
WORKDAY.INTL is asserted to error.
EOMONTH, EDATE, WORKDAY(.INTL), NETWORKDAYS(.INTL), YEARFRAC, WEEKNUM, the
coupon, bond and T-bill functions, DISC, BIN2DEC, IM* and the other Analysis
ToolPak functions give #VALUE! in Excel 365 for a reference to more than one
cell in a value argument, in dynamic-array and legacy formulas alike, where
GridCraft lifted the range and spilled. Array constants and computed arrays
still lift, and range arguments (holidays, cash flows, schedules) and the
.INTL weekend still take ranges.
FnSpec gains a value_args mask, filled at registration from one table in
lift.rs; call_lifted turns a multi-cell reference at a value position into a
scalar #VALUE! before lifting, so EOMONTH(A1:A3,{1;2}) is a 2x1 array of
#VALUE! as in Excel.

Excel 365 reads a dollar sign before accounting parentheses ($(1,234),
$ (5)) and a percent sign after them ((5)%) as negative numbers when the
text is typed, coerced by arithmetic or passed to VALUE. GridCraft gave
#VALUE! for these.
The parentheses branch no longer recurses: Excel reads only an unsigned
plain number or fraction inside, so (-5), ((5)), ($-5), and dates or
times in parentheses are now #VALUE! as in Excel (they used to give 5
or a negative serial). $5% is #VALUE! too: Excel never combines the
currency and percent signs.

MATCH, XMATCH, VLOOKUP, HLOOKUP, XLOOKUP and LOOKUP compared numbers at
15 significant digits (through compare / compare_numbers), so a computed
key such as =0.1+0.2 (0.30000000000000004) found 0.3. Excel 365 compares
lookup keys exactly in exact, approximate and binary search modes, while
=, SWITCH and the criteria functions (COUNTIF(S), SUMIF(S), AVERAGEIF,
MAXIFS) keep the 15-digit comparison. Observed in Excel via COM with
synthetic values.
lookup_equal now compares numbers with ==, and the lookup searches order
values with lookup_order (exact for numbers, compare otherwise).
compare_numbers and the criteria path are unchanged.
