feat(extract): --purge-proprietary --json for machine-readable purge report

Browse source 
Schema:

  asset_extract --purge-proprietary Data --json
  {
    "dir":         "Data",
    "confirmed":   false,
    "candidates":  21570,
    "removed":     0,
    "totalBytes":  17175328768
  }

"candidates" = files where a sidecar exists and is at least as
new (would be deleted on --confirm-purge). "removed" reflects the
actual delete count when --confirm-purge is set; 0 in dry-run.

Lets CI scripts gate on the dry-run candidate count before actually
purging:

  count=$(asset_extract --purge-proprietary Data --json | jq .candidates)
  [ "$count" -gt 1000 ] && asset_extract --purge-proprietary Data --confirm-purge

The asset_extract --json flag now applies to both upgrade and purge
modes.
