chore(deps): upgrade to Go 1.27 (#5990)

* build: upgrade to Go 1.27

Bumps the toolchain in go.mod, both golang base images in the Dockerfile, and
the devcontainer VARIANT. CI needs no change, as the workflows resolve the
version through go-version-file: go.mod.

Tests, race tests, build and vet all pass on go1.27.0.

* build: upgrade golangci-lint to v2.13.0

v2.13.0 is the first release built with Go 1.27, so it can lint a module whose go
directive is 1.27. It also enables gosec's G404 on math/rand/v2, which flags the
three rand.Shuffle call sites. Shuffle order is not a security decision, and the
crypto-backed alternative in utils/random costs 25x and allocates per swap, so the
call sites are annotated rather than the rule excluded, keeping G404 active for the
cases where it would matter.

* chore(deps): update Go dependencies to latest versions

* build: bump golangci-lint to v2.13.2
