mseries-sdk-apps

The M-series app SDK (rust/msdk, rust/msdk-gtk) and the Rust apps built on it, kept together so SDK and app changes land in one PR.

Extracted with history from techmore/ElementaryOS_MSeries (dev). The OS image, kernel, compositor and Vala plugins stay there.

• Signal Pantheon (native Vala/GTK 4 Signal client over signal-cli): mseries/signal-pantheon (imported with history from techmore/signal-pantheon; build with meson, see its README)
• Torrential (Relm4/Granite torrent client, own Cargo workspace so its dependencies stay out of the others): rust/torrential (imported with history from techmore/torrential, branch mseries-native)
• SDK and app-building docs: mseries/SDK-*.md, mseries/APP-BUILDING-GUIDE.md, mseries/RUST-PANTHEON-SDK.md
• Apps outside the Rust workspace: mseries/polybagger-print-manager (PolyBagger T1000 label printing; printer-link notes in docs/polybagger-t1000-printer-link-troubleshooting.md)
• Battery app and history logger: mseries/battery (docs mseries/BATTERY-*.md, mseries/install-battery.sh). The Wingpanel patches (panel-power-battery-history.patch, panel-power-battery-eta.diff) and install-battery-eta.sh's helpers (lib-backup.sh, lib-build.sh, patches/) belong to the OS image repo, so that script only works from there.
• Image Studio (native Rust/Granite image generation UI): rust/mseries-image-studio, backend contract in mseries/image-studio/README.md
• Messages: Rust app rust/mseries-messages; Python frontend and phone setup mseries/phone-setup; MCP server mseries/messages-mcp; status/parity notes mseries/MESSAGING-STATUS.md, mseries/MESSAGES-PARITY.md; installers mseries/install-phone-setup.sh, mseries/install-messaging-bluez.sh
• Workspace: rust/ (cd rust && cargo test -p msdk)
• SDK tests and bench: mseries/sdk-tests, mseries/sdk-bench

Layout is unchanged from the source repo on purpose; flattening paths is a later step. msdk.yml still references the Vala sources mseries/codexbar-wingpanel and mseries/dock-taskbar, which remain in the OS repo.

rust/pantheon-compositor/protocol/pantheon-desktop-shell-v1.xml is a vendored copy of the compositor's shell protocol, which msdk-gtk builds against. The OS repo is the source of truth; update this copy when the protocol changes.
