fix: remove continue-on-error from reusable workflow calls in ci.yml

continue-on-error is not supported on jobs that use reusable workflows
(uses: at job level). GitHub silently rejects the entire workflow file,
causing all repos to fail with "workflow file issue" and 0 jobs.

Lint and security jobs are already non-blocking since no other jobs
depend on them via needs:.
