iOS: declare ITSAppUsesNonExemptEncryption=false (open-source exemption)

Hash Bags' crypto is either OS-provided (TLS / CryptoKit / CommonCrypto)
or standard published algorithms shipped as MIT-licensed open source
(secp256k1, ed25519, SHA-2/3, AES, Argon2, ChaCha20). All of that
qualifies as "exempt" under BIS export controls (§740.17(b)(3)).
Declaring the answer in Info.plist skips the per-build App Store Connect
encryption questionnaire and removes the annual BIS self-classification
filing requirement.

Bump 1.0.0+4 -> 1.0.0+5 in case +4 already claimed an Apple build slot.
