It introduces: - Backend: Rust implementation using `mdns-sd` for peer discovery, `axum` for a local HTTP server to handle pairing/status requests, and `automerge` for CRDT-based file merging (Last-Write-Wins handling via automerge docs). - Frontend: A new Svelte component `SyncSettings.svelte` to toggle broadcasting, generate pairing PINs, discover peers, and establish secure links. The UI is integrated into the BottomSidebar. - Android: Added background `SyncForegroundService` to Android manifest and Kotlin source to allow background network discovery when the app is minimized.

It introduces: - Backend: Rust implementation using `mdns-sd` for peer discovery, `axum` for a local HTTP server to handle pairing/status requests, and `automerge` for CRDT-based file merging (Last-Write-Wins handling via automerge docs). - Frontend: A new Svelte component `SyncSettings.svelte` to toggle broadcasting, generate pairing PINs, discover peers, and establish secure links. The UI is integrated into the BottomSidebar. - Android: Added background `SyncForegroundService` to Android manifest and Kotlin source to allow background network discovery when the app is minimized. Fixed minor unused import warnings discovered during code review.

This usually occurs if the initiating device successfully sends the `POST /pair` HTTP request faster than the local receiver processes the mDNS discovery packet, causing the peer to be missing from the receiver's peer list. - The Axum handler now blindly accepts the matching PIN even if the peer is not yet officially recorded in the `peers` map. - Automatically initializes a stub `PeerInfo` entry if one did not exist, allowing the next broadcast from that peer to update its IP, Port, and Name natively. Also successfully rebased and integrated the remote changes as requested.

Note: CRDT payload generation is currently stubbed out (pending full integration with Automerge in a future commit).

Previously, the `POST /sync` request from the frontend saved a dummy stub payload, and the receiving end logged it without saving. - Modified `sync_file` command to actually read the file contents from the file system disk and push that byte slice over HTTP. - Modified `/sync` route handler on the receiving peer to save incoming modifications into `~/.cherit-sync-inbox/` directory (via `dirs` crate). Note: Saving directly to an inbox provides immediate visibility that the sync succeeds across the network without accidentally overwriting the root workspace until full CRDT state merging is connected.

This ensures character-level conflict resolution logic correctly preserves history without blowing up memory. - Live Sync Updating: When an incoming payload merges successfully, the backend emits a `sync-file-updated` Tauri event. The `text_editor` Svelte component intercepts this event, reads the new file from disk, and dispatches the change immediately into the CodeMirror editor instance. - Graceful Shutdown: Added a `broadcast` channel to gracefully signal and kill the background `axum` tokio task when stopping the sync service. - Persistent Peers: Serialized the internal `peers` map to a `peers.json` inside the platform-native app data config folder. - Path Serialization: Fixed a bug where Windows systems would send escaped backward-slash paths (`\\`) that macOS/Linux peers could not parse. - Android Background Hook: Implemented Android mobile plugin invocation to spawn the background service notification to keep network sockets alive.

If a sync event was triggered for it, the content was not properly parsed into an `ObjType::Text` before generating the sync payload. - Updated `load_or_create_doc` to inject the existing plaintext content into the newly minted CRDT Text object using `splice_text` if the file is found on disk. - Updated the backend `/sync` route to initialize the parent directories and create the plaintext file automatically if it receives a payload for a file that doesn't yet exist in the receiver's workspace.

Instead of relying solely on the active Svelte editor to push updates, the backend now watches the workspace using `notify-debouncer-full` and asynchronously syncs external changes seamlessly. - Device discovery feels significantly faster. Cached peers are proactively probed via HTTP instead of waiting up to 3 seconds for the next mDNS multicast cycle. - Fixed device naming. Hostnames are properly derived using `gethostname` instead of `Device-PIN`. - Svelte UI now allows renaming and deleting known peers to provide control over persistent trust data.
