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.

Vendored arti.xcframework rebuilt from source (Rust 1.96.0, normalized
archive metadata for reproducible hashes). New ARTI-BINARY-PROVENANCE.md
records toolchain, rebuild steps, and a SHA256 manifest for every file
in the xcframework. A new CI workflow turns that policy into a gate:
PRs must keep the binary matching the manifest, and binary changes must
ship with source/lockfile/build-script evidence.
Also raises TorManager.awaitReady's default timeout from 25s to 75s to
match the bootstrap monitor deadline - a shorter wait reported "not
ready" while Arti was still legitimately bootstrapping, silently
stranding queued relay work.
Privacy policy, Tor integration doc, and privacy assessment updated to
match the current implementation.

- Replace C Tor (0.4.8.21) with Rust Arti (1.9.0/arti-client 0.38)
- 70% smaller binary: 21MB xcframework vs 67MB (6.9MB vs 14MB per slice)
- Memory-safe Rust implementation with modern async (tokio)
- Same SOCKS5 proxy interface at 127.0.0.1:39050 for drop-in compatibility
- FFI wrapper (arti-bitchat crate) with C-compatible exports
- Swift TorManager maintains identical public API
- Aggressive size optimization: opt-level=z, lto=fat, panic=abort, strip
- Supports iOS device, iOS simulator (Apple Silicon), and macOS
