Peach Android v2.17.38

Security and assurance fixes

• Cloud-backup extraction now excludes the sync-generation archive consistently with legacy backup and device-transfer rules.
• Native Noise provenance documentation now identifies the current product version.
• Backup decode tests generate a synthetic encrypted PeachScript fixture instead of depending on a developer-local Downloads file.
• Android Argon2id coverage now includes an exact browser known-answer vector.

Verification

• XML syntax validation passed for the updated extraction rules.
• Focused remediation tests were added; full JVM and lint verification follows the repository gate.
