Correct the security claims in docs and comments, and record the accepted risks (closes #171)

Docs and comments only; no behaviour change. Corrects ten overclaims the
security review found: snapshot names are hashed but the hash uses no
secret, so a guessed hostname and name can be confirmed; a blob is named
by hex(SHA256(SHA256(uncompressed contents))), stated once in
docs/REPOSTRUCTURE.md and referenced elsewhere; double hashing does not
hide known content (blob packing does); age uses ChaCha20-Poly1305, not
XChaCha20; encryption is required, not optional; a snapshot is marked
complete before its metadata is uploaded; the export comment now matches
its only caller; deep verify detects corruption, not authorship; adding a
recipient does not reach existing data; restore examples target a
user-owned directory.

Adds an Accepted Risks subsection under Security Considerations with the
seven documented risks, cross-referenced from the README.

-  commands wrote plain text straight to stdout, so they were unstyled and

-  `internal/ui`: status lines and confirmations go through its message
-  methods (styled, and `--quiet` silences them), while the data a command
-  exists to produce — the reports, the `snapshot list` table, `config get`
-  values, and the `--json` documents — is written plain. `--quiet`
-  silences the human reports and tables but never the `config get` value
-  or the `--json` documents, which a script depends on, and the

-  output-style section now states this rule.

 3. **Metadata is written atomically** - Both db.zst.age and manifest.json.zst are written as complete files
-4. **A snapshot is marked complete in the local DB only after its metadata is uploaded** - `finalizeSnapshotMetadata` runs `ExportSnapshotMetadata` first and records completion (`MarkSnapshotComplete`) only once the export succeeds (see the backup data flow in [ARCHITECTURE.md](../ARCHITECTURE.md)). A crash during the export therefore leaves the snapshot incomplete, so the next backup's `PruneDatabase` drops it and re-backs-up its data, rather than leaving a completed-looking row in the local index with no matching metadata on the destination store. (A crash in the brief moment after the export succeeds but before completion is recorded leaves a fully-restorable snapshot on the destination that the local index drops as incomplete on the next run; `snapshot list` then reports it honestly as remote-only, which is the safe direction: the destination copy stays restorable.)
+4. **A snapshot is marked complete in the local DB before its metadata is uploaded, not after** - `CompleteSnapshot` runs first, then `ExportSnapshotMetadata` (see the backup data flow in [ARCHITECTURE.md](../ARCHITECTURE.md)). A crash between the two leaves a completed-looking row in the local index with no matching metadata on the destination store. `vaultik prune` reconciles this away: it drops any local snapshot whose remote metadata is missing.
