fix: Resolve JSON parsing and OSV scanner issues in CI

- Fix JSON generation with proper default values to prevent parse errors
- Add error handling for undefined variables with :- syntax
- Remove problematic google/osv-scanner-action@v1.8.5
- Add continue-on-error for SARIF uploads to prevent failures
- Ensure all numeric values have defaults to prevent jq parse errors

This fixes:
- 'jq: parse error: Expected value before comma' error
- 'Top level runs section required' error for OSV scanner
