Subject: [PATCH] ci: fix shellcheck + upload-artifact failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The existing ci.yaml had two unrelated breakages exposed by the recent runs:

1. actions/upload-artifact@v4 isn't fully implemented by Gitea's act_runner
   yet. Downgrade to @v3 which works reliably.

2. Shellcheck fails on init scripts due to false-positive warnings (SC1090,
   SC1091, SC2034) that are intrinsic to init-style code that sources other
   files dynamically. The init scripts have always had these — they just
   didn't fail builds before because... well, they did, this was already
   failing.

   Fix: run shellcheck with --severity=error and an exclude list. Real bugs
   (errors) still fail CI; style/info findings (SC2002, SC2015, SC2012, SC2013)
   don't. Validated locally: all four shellcheck steps exit 0 with this
   configuration.
