Merge branch 'main' into chore/perf-privacy-polish

The unpinned setup-swift action installs Swift 6.1, which refuses the
SDK on runner images that have rolled to Xcode 26.5 ("this SDK is not
supported by the compiler"). Jobs passed or failed depending on which
image they landed on. The Xcode-bundled toolchain always matches the
image's SDK, and matches local development. Cache keys now include the
toolchain version so artifacts from one compiler are never restored
into builds with another.

+
+## Architecture Overview
+
+BitChat is a **dual-transport P2P messaging app**: Bluetooth mesh for offline local communication, Nostr protocol for internet-based global messaging.
+
+### Local Packages (`localPackages/`)
+
+- **BitFoundation**: Shared foundation types — `BinaryProtocol` (compact binary packet format for BLE), `BitchatPacket`, `BitchatMessage`, `PeerID`, hex/SHA256/compression utilities. Has its own test suite under `localPackages/BitFoundation/Tests` (run `swift test` inside the package).
+- **BitLogger**: `SecureLogger` logging.
+- **Arti**: Tor integration (exposes the `Tor` product).
+
+### Transport Layer
+
+- **BLEService** (`bitchat/Services/BLE/BLEService.swift`): Core Bluetooth LE mesh networking - peer discovery, connection management, multi-hop relay (max 7 hops), packet fragmentation. The BLE directory contains ~40 focused collaborators (handlers, policies, buffers): `BLEReceivePipeline` dispatches inbound packets to `BLEAnnounceHandler` / `BLENoisePacketHandler` / `BLEPublicMessageHandler` / `BLEFragmentHandler` etc.; outbound planning lives in the `BLEOutbound*` types; peer state in `BLEPeerRegistry`.
+- **NostrTransport** (`bitchat/Services/NostrTransport.swift`): Internet transport via Nostr relays with NIP-17 encryption
+- **Transport protocol** (`bitchat/Services/Transport.swift`): Common interface both transports implement
+
+### Encryption Layer
+
+- **NoiseProtocol** (`bitchat/Noise/`): Noise XX pattern for end-to-end encryption with forward secrecy
+  - `NoiseEncryptionService`: Main encryption/decryption API
+  - `NoiseSessionManager`: Thread-safe per-peer session management
+  - `NoiseSession`: Individual peer session state (handshake, send/receive ciphers)
+- **NostrProtocol** (`bitchat/Nostr/NostrProtocol.swift`): NIP-17 gift-wrapped encryption for Nostr messages
+
+### Protocol Layer
+
+- **BinaryProtocol** (`localPackages/BitFoundation/Sources/BitFoundation/BinaryProtocol.swift`): Compact binary packet format for BLE (lives in BitFoundation, not `bitchat/Protocols/`)
+- **BitchatProtocol** (`bitchat/Protocols/BitchatProtocol.swift`): Message types and packet structures
+- **LocationChannel/Geohash** (`bitchat/Protocols/`): Geographic channel routing
+
+### Application Layer
+
+- **AppRuntime** (`bitchat/App/AppRuntime.swift`): Composition root. Owns `ChatViewModel`, `ConversationStore`, the feature models (`PublicChatModel`, `PeerListModel`, `LocationPresenceStore`, `PeerIdentityStore`, ...), and the app event stream.
+- **ConversationStore** (`bitchat/App/ConversationStore.swift`): Single-writer, single source of truth for conversation message state and selection (see `docs/CONVERSATION-STORE-DESIGN.md`). Feature models and `ChatViewModel` observe it and mutate it through its intent API.
+- **ChatViewModel** (`bitchat/ViewModels/ChatViewModel.swift`, ~1,600 lines): Central coordinator that wires and delegates to ~25 focused coordinator/pipeline types in `bitchat/ViewModels/`, e.g.:
+  - `ChatPrivateConversationCoordinator` / `ChatPublicConversationCoordinator`: DM and public chat flows
+  - `ChatNostrCoordinator` → `GeohashSubscriptionManager`, `NostrInboundPipeline`, `GeoPresenceTracker`, `GeoChannelCoordinator`: Nostr/geohash channel logic
+  - `ChatOutgoingCoordinator`, `ChatDeliveryCoordinator`, `PublicMessagePipeline`: send paths and delivery tracking
+  - `ChatMediaTransferCoordinator`, `ChatMediaPreparation`: media transfers
+  - `ChatLifecycleCoordinator`, `ChatTransportEventCoordinator`, `ChatPeerListCoordinator`, `ChatPeerIdentityCoordinator`, `ChatVerificationCoordinator`: lifecycle, transport events, peer state
+  - `bitchat/ViewModels/Extensions/` (`ChatViewModel+Nostr/+PrivateChat/+Tor`): thin delegation shims kept for call-site stability; the real logic lives in the coordinators
+- **MessageRouter** (`bitchat/Services/MessageRouter.swift`): Intelligent transport selection (BLE → Nostr fallback)
+- **PrivateChatManager** (`bitchat/Services/PrivateChatManager.swift`): DM session management
+
+## Test Infrastructure
+
+Tests use an **in-memory networking harness** for deterministic, race-free testing:
+
+- **MockBLEService** (`bitchatTests/Mocks/MockBLEService.swift`): Simulated BLE mesh with configurable topology
+  - `MockBLEService.resetTestBus()` - Clear state in setUp()
+  - `simulateConnectedPeer(_:)` / `simulateDisconnectedPeer(_:)` - Configure topology
+  - `autoFloodEnabled` - Enable broadcast flooding for Integration tests only
+
+- **Test categories**:
+  - `bitchatTests/EndToEnd/`: Full message flow tests with explicit routing
+  - `bitchatTests/Integration/`: Multi-node topology tests with auto-flooding
+  - Unit tests: Individual component tests
+
+## Key Patterns
+
+- **Threading**: Use `@MainActor` for UI, `Task { @MainActor in ... }` for main thread dispatch
+- **Delegation**: `BitchatDelegate`, `TransportPeerEventsDelegate` for event propagation
+- **Session recovery**: On decrypt failure, clear local session and re-initiate Noise handshake (no NACK)
+
+## Device Setup
+
+To run on physical devices:
+1. Copy `Configs/Local.xcconfig.example` to `Configs/Local.xcconfig`
+2. Add your Developer Team ID to `Local.xcconfig`
+3. Replace `group.chat.bitchat` with `group.<your_bundle_id>` in entitlements
