Mechanical style fixes across the enabled rule set, mostly via
swiftlint --fix (trailing_comma, comma, colon, trailing_newline,
comment_spacing, unused_closure_parameter, unneeded_break_in_switch,
opening_brace) plus hand fixes:
- non_optional_string_data_conversion (45): .data(using: .utf8)! and
?? Data() fallbacks replaced with the non-optional Data(_.utf8),
including two production sites (NIP-44 HKDF info constant and the
announce canonicalization context/nickname bytes — byte-identical
output, only the impossible-nil handling is gone).
- switch_case_alignment: LocationChannel had a misindented closing
brace; also repaired an --fix artifact in BLEService's .none case.
- redundant_string_enum_value: TrustLevel raw values equal to the case
names (encoded form unchanged).
- unused_optional_binding: let _ = binds replaced with != nil / is Bool.
- static_over_final_class: PreviewView.layerClass.
- Resolved the BinaryProtocolTests TODO by documenting that 8-byte
recipient ID truncation is the fixed wire-field size, not a bug.
The 4 remaining violations are all todo markers for a shared
test-helpers module (tracked in #1088) and one Reuse note.

precondition() crashes the app in release builds if violated. This is
dangerous for cryptographic code that may receive malformed input from
network data or key derivation bugs.
Changed to guard statements that throw typed errors instead:
- XChaCha20Poly1305Compat.Error.invalidKeyLength
- XChaCha20Poly1305Compat.Error.invalidNonceLength
This allows callers to handle errors gracefully rather than crashing.
* NIP-17/44: adopt NIP-44 v2 (XChaCha20-Poly1305, v2: base64url), switch rumor kind to 14, randomize BIP-340 aux; add XChaCha20Poly1305Compat and wire-up
* Nostr DMs: ensure delivered/read acks are sent even without Noise key mapping by falling back to direct Nostr (geohash-style) acks to sender pubkey
* NIP-44 v2 decrypt: try both Y parities for x-only sender pubkeys (even then odd) to fix unwrap authentication failures
* Tests: add NIP-44 v2 ACK round-trip tests (delivered/read) using bitchat1 embedding and gift-wrap decrypt path
* UI: fix DM autoscroll IDs by using dm:<peer>|<id> for private chat item IDs and preserve anchors, ensuring scrollTo targets exist when opening/switching/new messages
* UI: fix string interpolation in DM/geohash context keys (remove escaped interpolation) to resolve 'unused ch' warnings and ensure proper IDs
* UI: MeshPeerList shows transport state icon: radio for mesh-connected, purple globe for mutual favorite/Nostr; fallback dim person for others
