CI: fix dead scrutinizer-ci.com/ocular.phar URL

[aik099]

Problem

Every CI job currently fails, on every branch/PR, regardless of the actual code change. The "Upload Coverage to Scrutinizer CI (PHP < 8.0)" step runs:

wget https://scrutinizer-ci.com/ocular.phar

which now returns 403 Forbidden — this endpoint appears to be dead. wget exits non-zero and fails the whole job, even though vendor/bin/phpunit itself passes cleanly right before it (visible in the logs of every currently-failing job, e.g. PR #114).

Only the PHP < 8.0 step is affected — the PHP >= 8.0 step installs scrutinizer/ocular via Composer instead and never hits that URL.

Fix

Point wget at the GitHub Releases copy of ocular.phar instead:

-  wget https://scrutinizer-ci.com/ocular.phar
+  wget https://github.com/scrutinizer-ci/ocular/releases/download/1.6.0/ocular.phar

Verified the URL resolves and serves the file (200 OK). Same fix already applied in a sibling repo, console-helpers/svn-buddy (commit 7a34548, "Use "ocular.phar" from GitHub CDN").

Closes #112
