/members endpoint returns incomplete results for large bundles (only latest releases) - M20 navcam_ops_stereo

🐛 Describe the bug

The /members endpoint for the bundle urn:nasa:pds:mars2020_navcam_ops_stereo is returning only 176,269 files (releases 14 and 15 only), whereas the full bundle should contain 2,233,883 files across all releases. This is causing downstream impact on NSSDCA Deep Archive SIP generation — the SIP tool (pds-deep-archive) is only picking up the newest releases instead of the full mission.

This is most likely tightly coupled with the ancestry sweeper issues documented in NASA-PDS/registry-sweepers#171 and #717, where ancestry is not being properly written for all products/releases, causing the /members endpoint to return incomplete results.

🕵️ Expected behavior

The /members endpoint should return all members across all releases of the bundle (~2,233,883 files), not just the newest releases.

📜 To Reproduce

1. Go to https://pds.mcp.nasa.gov/api/search/1/products/urn:nasa:pds:mars2020_navcam_ops_stereo
2. Note the bundle properties
3. Go to https://pds.mcp.nasa.gov/api/search/1/products/urn:nasa:pds:mars2020_navcam_ops_stereo/members
4. Only 176,269 files are returned (releases 14 and 15 only); expected ~2,233,883 files (all releases)

🩺 Test Data / Additional context

Downstream impact: NSSDCA Deep Archive SIP generation is incomplete — the SIP only contains the newest releases instead of the entire mission bundle, requiring a new complete SIP to be regenerated.

@alexdunnjpl I am assuming this is the same issue as all the others with sweepers?
