chore(ci): stop release and CodeQL runs on PRs, drop deploy smoke tests

The release matrix (7 Linux cross-builds + a CGO Windows build) ran on every
PR and on every branch push, so a PR from a repo branch built everything
twice. Release binaries now build only on main (dev channel) and version
tags; any other branch can still be built via workflow_dispatch.

CodeQL keeps its push-to-main and weekly scans but no longer runs per PR.

The deploy smoke workflow fired on every Release completion only to skip
its jobs; deploy/test/smoke-noninteractive.sh stays for manual runs.

-# Container smoke test for the unattended (cloud-init) install path.
-# Runs when the install/deploy assets change on a branch push or PR, and
-# again after a release-tag build finishes uploading its assets — passing the
-# tag as an explicit version, so the green result verifies the release
-# actually being shipped. That job deliberately runs the script from the
-# default branch rather than checking out the tag: workflow_run executes in
-# main's cache scope, so executing checked-out code there is a cache-poisoning
-# surface (CodeQL actions/cache-poisoning/poisonable-step), and users pipe
-# main's install.sh anyway.
-# Tag pushes must NOT trigger the unpinned job directly: at that moment
-# releases/latest still points at the previous release (#5756), and a `paths`
-# filter alone cannot exclude them because a brand-new tag ref has no diff
-# base, so it runs on every tag push.
