feat: add nub package manager support

[2u841r]

Summary

• Adds nub (https://github.com/nubjs/nub) as a selectable package manager alongside npm/pnpm/yarn/bun/deno/vlt/vp
• Wires it into the install/execute command builders (nub add, nubx, nub create), the PM dropdown selector, and the terminal install/execute displays
• Closes Add support for nub package manager #3013

Icon

nub has no standalone logo file in its repo root, but the project's site repo (site/public/icon.svg in nubjs/nub) has one: a black rounded-square badge with a cream "n" glyph and an orange accent dot.

To match the existing icon set's aesthetic (vlt, a11y, etc. in assets/media/custom-icons.json), which are all flat, single-color glyphs that inherit currentColor so they follow the app's theme:

• Dropped the background square and hardcoded colors (black bg, cream glyph, orange dot)
• Kept just the "n" glyph + accent dot paths, recolored to fill='currentColor'
• Cropped the viewBox from the original 0 0 32 32 down to a tight 5 4 23 23 around the glyph's actual bounding box — the original had padding built in for the (now-removed) background square, so without cropping the glyph rendered noticeably smaller than the other PM icons at the same h-3 w-3 size

Test plan

• test:types passes
• pnpm test passes (1693/1693 unit + component tests)
• Verified nub option appears and works in the PM dropdown, install command box, and execute command box locally
• Reviewer: confirm nub icon renders correctly and matches sizing of other PM icons

Walkthrough
