Update landingkit to v0.3.0 and add its two brand keys

[tannevaled]

Bumps github.com/go-fleettools/landingkit to v0.3.0 and appends the two brand keys it reads, so the last two cyan literals follow the logo: statsEnd = "#fbd2d2" and bandText = "#fce1e1".

The two lines are what landingkit brand static/img/logo.svg prints at v0.3.0. Every existing key in [params.brand] is byte-identical to its output, and the block's comments are kept.

Verification

<style> diff, main vs this branch, both built with pkgx hugo@0.167.0:

• .grid>*{min-width:0} added and .card gains overflow-wrap:anywhere (v0.3.0 layout fix)
• .stats .n gradient end: #cdf1fa -> #fbd2d2
• .band p colour: #d8f3fb -> #fce1e1

Outside <style>, the only change is whitespace: v0.3.0's partials no longer end with a newline (the GitHub icon's trailing newline before the button text).

go.mod still requires the module after go mod tidy (kept by kit.go). landingkit verify (text and pixels) and a 390px no-sideways-scroll check follow in a comment.

Verification of this branch:

landingkit verify -hugo "pkgx hugo@0.167.0" <this site> <go-fileshare.github.io on its v0.3.0 branch>, with pixels:

PASS the <style> block equals the reference's once brand values are masked
PASS light: 62/62 background pixels identical (#ffffff)
PASS dark: 62/62 background pixels identical (#0b0e14)

(Local Chrome under heavy load exits with status 2 after writing its output; it was run through a wrapper that accepts that exit only when the requested output exists. It did so 0 times in this run.)

At 390px, puppeteer device emulation (setViewport({width:390, isMobile:true})) on the built branch: no sideways scroll (scrollWidth 390, clientWidth 390, scrollX after scrollTo(100,0) = 0).
