Phase 0: skeleton, streaming encryption (spike A)

Browse Source 
Repository skeleton (app id ng_backup, AGPL-3.0-or-later), KeyRing with
KDF subkeys, keyed blob ids and Argon2id key wrapping, and StreamCipher
(secretstream XChaCha20-Poly1305, framed, bounded memory).

Spike A: 1 GiB round trip with memory_limit=64M, peak < 2 MiB, ~160/122
MiB/s; tampering, truncation, wrong key/passphrase are rejected.

# NG Backup
Encrypted, incremental backups of Nextcloud with restore from the web interface.
Works without shell access: no external programs, no extra PHP extensions beyond sodium.
**Status: phase 0 (prototype). Not usable yet.** See `PLAN.md` for the design.
