Disable CodeQL for push/PR events due to Scala/SBT incompatibility

CodeQL's Java tracer doesn't properly capture Scala/SBT compilation
because SBT doesn't use javac in the traditional way. This is a known
limitation (github/codeql-action#859).

CodeQL will still run on schedule (weekly) and can be manually triggered.
The main CI workflow (lint, build, test) is now fully functional.
