feat(bazel): add Bazel plugins and completion

Add vim-bazel (with its vim-maktaba dependency) and bazel.nvim for
running Bazel from the editor, with an errorformat that sends Bazel
build and test failures to the quickfix list. cmp-bazel supplies a
Bazel completion source, wired into blink.cmp through blink.compat.
lazy-lock.json pins the five new plugins.
