Fix skill-validation workflow failing when agents directory is deleted#13592

The filter step deletes .github/agents/ when no agent files are changed in the PR. Later, the step summary and metadata steps run: find .github/agents -name '*.agent.md' 2>/dev/null | wc -l find returns exit code 1 on a missing directory. 2>/dev/null suppresses the error message but not the exit code. Under -o pipefail (set by the shell: bash --noprofile --norc -e -o pipefail), the pipeline exit code is 1. Under set -e, this terminates the script before reaching exit \\\, causing the step to report failure even though the validator printed 'All checks passed'. Add || true to all four find|wc pipelines so a missing directory produces a count of 0 instead of aborting the script. Fixes the same issue for .github/skills/ which can also be deleted when only agent files are changed.

Pull request overview
This PR fixes a GitHub Actions workflow failure in .github/workflows/skill-validation.yml when the workflow’s filtering step removes .github/skills/ and/or .github/agents/, causing later find | wc pipelines to terminate the step under bash -e -o pipefail.
Changes:
- Make the four
find … | wc -lcount pipelines resilient to missing directories by appending|| true. - Ensure both the step summary output and the metadata/artifact output paths report counts as
0instead of failing the job.

✅ 24/24 dimensions clean — no findings.
Summary: The || true additions are correct and necessary. GitHub Actions bash steps run with -e -o pipefail, so when find returns non-zero (directory doesn't exist), pipefail propagates the failure through wc -l, and set -e aborts the step. The fix ensures the count command substitutions always succeed while still capturing the correct wc -l output (|| true produces no stdout, so the captured value is unaffected). This is idiomatic shell and consistent with the existing || echo "(none)" pattern used elsewhere in the same workflow (lines 110-112).
