Adds a 'Preview' display role alongside the existing 'Wall' role. Each monitor can be assigned a role in the setup wizard: - Wall: the public grid (e.g. 2x2 on the external display) - Preview: a larger operator grid (default 3x4 = 12 cells) on a laptop Double-clicking any cell in a Preview display fills that laptop screen with the selected video. Escape (or another double-click) returns to the preview grid. The wall grid keeps playing independently. Also persists preview grid size and per-display roles in config.ini. Version bumped to 10.15.0.
Implements the core changes for preview displays: - constants.DisplayRole with WALL/PREVIEW values - HyperwallConfig gains last_preview_rows/cols and last_display_roles - SetupWizard lets users assign Wall/Preview role per monitor and set preview grid size - WallController builds wall vs preview windows with different grid sizes - VideoCell emits request_solo on double-click - WallController enters/exits solo fullscreen on preview displays; Escape exits solo - app.py wires new settings through and persists them - version bumped to 10.15.0
Adds a TCP/JSON sync mesh so multiple Hyperwall instances can cooperate. - New hyperwall/sync.py: SyncServer + SyncClient, newline-delimited JSON protocol with hello/full_state/cell_update/solo/exit_solo/filter/remote_solo. - Config options: sync_enabled, sync_server, sync_host, sync_port, sync_display_name (defaults: off, port 9876). - WallController gains per-cell and per-display UUIDs, sync adapter hooks, and applies remote state changes on the GUI thread. - Local state changes (next/prev/filter/solo/exit solo) are broadcast to peers. - Remote solo: Ctrl+double-click a preview cell asks the server to fullscreen that item on every other peer's first display. - App starts server or client based on config and attaches the adapter. - Adds tests/test_sync.py covering framing, hello, broadcast, filter, and remote-solo routing. All portable tests pass; Qt-dependent tests still run on Windows build job.
Integrates the sync layer added in the previous commit: - cell.py: request_remote_solo signal + Ctrl+double-click handler. - wall.py: cell/display UUIDs, sync_broadcast_* helpers, sync_apply, _remote_solo, and adapter lifecycle in _cleanup. - config.py: persists sync_enabled/server/host/port/display_name. - app.py: starts SyncServer/SyncClient and attaches adapter to controller. - tests/run_all.py: register test_sync.py suite.
- Add RelayController and run_sync_relay() for running the sync server headlessly on a LAN host (no Qt/mpv needed). - Fix SyncServer._build_full_state to read relay-stored state. - Add --sync-relay/--sync-host/--sync-port CLI flags to hyperwall.py. - Add scripts/run-hyperwall-relay.sh for mb.perseus.observer. - Add scripts/run-hyperwall-client-macos.sh and scripts/config.client.ini.template for Mark's macOS client. - Add RelayController tests. Full suite green.

Summary

Soak follow-up
The target macOS/Emby soak must be rerun after pulling this PR. The original report showed an upstream HLS/Emby HTTP-500 burst; this change prevents the client from adding transcoded prefetch load while the server transcode budget is exhausted.
