fix(colors): keep the number format when resetting colors - #682

What

Edit Colors' (r)eset and (c)lear all now reset only colors, bold and dim. A widget's number style (set with . in Edit Lines, or decimals in settings.json) stays.

Why

Number styles started out in Edit Colors (#456's first commit cycled them with n there) and the two reset paths were extended to clear them too. Later in the same PR the cycle moved to Edit Lines ("The color menu goes back to color, bold and dim only"), but reset and clear all kept removing numberFormat.

So resetting a widget's colors also undid its number style, with nothing on screen saying so: the key help just says (r)eset in a colors menu, and the clear-all confirmation says "This will reset all colors for all widgets to their defaults." With Context Length set to whole numbers, Edit Colors → ↓ to Context Length → r: the preview goes from Ctx: 19k to Ctx: 18.6k, and after ctrl+s the widget is saved as {"id": "3", "type": "context-length"}, with its numberFormat gone.

How

resetWidgetStyling and clearAllWidgetStyling no longer list numberFormat among the fields they remove. They still remove color, backgroundColor, bold and dim as before. Widgets without a number style are unaffected, and the global number format in Global Overrides was never touched by these keys.

Demo

Context Length set to whole numbers (the preview's sample data, 19k), then Edit Colors → Context Length → r. Before, the number goes back to 18.6k along with the color; after, only the color resets.

Testing

• The two existing tests in color-menu/__tests__/mutations.test.ts asserted that numberFormat was removed; they now expect it kept, alongside the color, bold and dim removal they already checked. Both failed before the fix.
• bun test: 2782 pass, 0 fail. bun run lint passes.
• The changed test file under Node 26.10.0 (Vitest): 7 pass.
• Built CLI under Node 26.10.0 in tmux with a scratch HOME, the steps above: main shows Ctx: 18.6k after r and saves the widget without numberFormat; this branch keeps Ctx: 19k and saves "numberFormat": {"style": "whole"}, with the color reset to the default (Bright Black) on both.
• Bun 1.4.2.
