Privacy hardening, remote-peer IP masking and review fixes

- Add privacy projection (core/privacy.py), private report storage, bounded
  process capture; omit identities, free text and unapproved paths
- Mask remote peer IPs: only loopback/host/wildcard stay numeric, others are
  reduced to remote_scope private/public (schema + scoring updated)
- Map ss TCP states to canonical names; ASCII-only numeric fields; fix
  "Microsoft Visual C++" product matching (Python and PowerShell)
- Merge 7fed3b9: -Diagnostic switch, serialization exit code 3, PS7 module
  path, UI error detail; keep hardened task/certificate collectors
- Add audit docs, privacy docs and regression tests
