PGPony: PGP & GPG Encryption

PGPony 8.2.0 brings iOS in line with the Android 4.2.0 and 4.3.0 releases. This is the largest update yet. POST-QUANTUM New ML-KEM-1024 with X448 keys, beside the existing 768 suite, in both the LibrePGP and v6 composite forms. Tested against GnuPG 2.5.x in both directions. Large post-quantum files now open on the streaming path, so size is no longer a wall. KEYS AND IDENTITIES Change a key's passphrase: add one, change it, or remove it, on v4, v6, and post-quantum keys. Multiple identities per key: add and revoke user IDs and choose your primary. Add subkeys, edit a key's expiration, and see each subkey's algorithm and capabilities in Key Detail. Editable identity proofs: add identity notations like proof@ariadne.id=... to your key, then verify a contact's proofs against HTTPS pages, GitHub gists, Mastodon profiles, and DNS records. Import now recognizes brainpool and NIST-curve keys from GnuPG and other tools. The import screen shows the full fingerprint in readable four-character groups. DELETING, SAFELY A key recycle bin: deleting a key moves it to Recently Deleted, restorable for 30 days, instead of destroying it outright. Deleting a key pair offers a backup first and asks for Face ID. Clear All Data is a deliberate, multi-step reset. Per-key fallback decryption keys and signing defaults, so the right key signs for each recipient and older recipients still get a signature they can verify. SENDING AND RECEIVING Streaming for large files and bundles: encrypt and decrypt multi-file bundles with flat memory use, and progress on big exports. Wrap encrypted output in a .zip for transports that mangle .asc and .gpg attachments. Decrypting a .zip just works. Animated multi-part QR: a large key now cycles across several QR frames automatically. Open a signed-but-not-encrypted file and verify it in place, instead of hitting an error. Fixed a WKD and keyserver import that failed to parse some keys, including certain Thunderbird keys. EVERYTHING ELSE Passphrase cache with a duration you choose, from one minute to until you clear it. Back up and restore your whole keyring, and import OpenKeychain backups. Fully localized in English, German, Spanish, French, Japanese, Brazilian Portuguese, Russian, and Simplified Chinese. Many of these came straight from user reports on GitHub and the board.
