Subject: [PATCH] ci: bump Go, golangci-lint, codespell, and runners

 * Test matrix: 1.24.x (go.mod minimum) and 1.26.x (latest); drop 1.25.x.
 * GO_VERSION for the validate jobs: 1.25 -> 1.26.
 * golangci-lint: v2.4 -> v2.12.
 * codespell: 2.4.1 -> 2.4.3.
 * Runners: ubuntu-24.04 -> ubuntu-26.04.

The actions themselves are already kept current by dependabot.
