fix: Resolve CI failures for v0.7.0 release

Fix lint errors:
- Remove unused Optional import from gitleaks workflow
- Remove unused logging import from trufflehog activities

Fix documentation broken links:
- Update workspace-isolation links to use /docs/ prefix in resource-management.md
- Update workspace-isolation links to use /docs/ prefix in create-workflow.md

Fix benchmark dependency:
- Add fuzzforge-sdk installation to benchmark workflow
- SDK is required for bench_comparison.py import

All CI checks should now pass.
