This PR moves the landing onto the shared landing kit, go-fleettools/landingkit v0.7.1. It is wave 6 of the fleet's migration, done with landingmigrate (go-fleettools/fleettools).

What changes

• The design comes from the kit. That means the nav bar, the hero, the fork ribbon, the dark mode and the hero carousel. The content stays as it was: the header becomes the hero, the first code snippet becomes the hero's terminal, and <main> keeps its own rules, scoped to .legacy.
• Removed: layouts/partials/icons/book.html, layouts/partials/icons/mark-github.html, layouts/partials/icons/OCTICONS-LICENSE, because the kit ships them, and a local copy would silently override the kit's.
• Added: go.mod and kit.go, so Renovate bumps the kit. hugo.toml gets the module import and a [params.brand] block read from the logo by landingkit brand.
• actions/setup-go is added to .github/workflows/hugo.yml, because hugo fetches the module with the go command.
• The mantra strip under the top bar shows LICENSE=BSD-3-Clause and CGO_ENABLED=0.

Repeats hidden while the strip shows

The strip already says these. Each is wrapped in {{ if not (partial "mantra-on.html" $) }}, so it comes back if the strip is ever turned off:

• pill: pure Go · zero cgo
• badge: (the licence badge)
• footer: BSD-3-Clause ·

Kept: these mention the licence or cgo and say more (please review)

• sentence: No cgo, no Prism.
• sentence: go-ruby-parser turns Ruby source into a syntax tree: a stateful lexer, a recursive-descent parser with a Pratt expression core, and a typed AST — all in pure Go, with cgo disabled.
• sentence: No cgo, no Prism, no shelling out to Ruby: the front-end the Go ecosystem lacked for building Ruby tooling (linters, formatters, analysers, doc generators, LSP servers, transpilers) in pure Go.
• sentence: A pure-Go, cgo-disabled front-end, so it cross-compiles and embeds anywhere — and, being CGO=0, also compiles to WebAssembly (js/wasm and wasip1/wasm).

Verified

I built the old page, the new page, and the new page with the strip off, then ran landingmigrate verify:

VERIFIED 88 text nodes, 10 links, 5 pictures of the old page kept; the strip-on page is the strip-off page minus 3 hidden repeat(s); the strip says LICENSE=BSD-3-Clause, CGO_ENABLED=0 as text

Every text node, link and picture of the old page is still on the new page. With the strip on, the page is the strip-off page minus exactly the hidden repeats.
