Summary

• Rename component property names from the deprecated osv-scanner: prefix to datadog: (e.g. osv-scanner:is-direct → datadog:is-direct, osv-scanner:package-manager → datadog:package-manager). This aligns property naming with the Datadog namespace and removes the dependency on the OSV Scanner naming convention.
• Remove the deprecated property name constants from models.go.
• Add a test case for reachable-symbol-location metadata to improve coverage of the CycloneDX output path.

Details

The buildDatadogProperty helper in internal/output/sbom/cyclonedx.go already used the datadog: prefix for dynamically built properties. This PR ensures all property names are consistently namespaced under datadog:, removing the remaining osv-scanner: and datadog-sbom-generator: prefixed names.

All snapshot files have been updated to reflect the new property names.

Test plan

• Existing snapshot tests pass with the updated property names
• New reachable-symbol-location test case passes
