Windows port carry-over: main/preload/scripts/patches/distribution/CI

[ElecTream]

Lands all the Windows-port work that was sitting in the working tree from the prior session. Required for npm install to succeed on a fresh clone: the postinstall script (referenced in package.json) lives here, as do the patches it applies and the scripts/dev.js wrapper that the dev script calls.

scripts/

• postinstall.js: cross-platform dispatcher. On any OS: applies patches via patch-package, then runs electron-builder install-app-deps. On macOS: also patches the dev icon. On Windows: no-ops past the rebuild.
• dev.js: replaces unset ELECTRON_RUN_AS_NODE && electron-vite dev (POSIX-only). Node wrapper that does delete process.env.ELECTRON_RUN_AS_NODE then exec's electron-vite. Works on Windows + macOS without cross-env's empty-string semantics issue.
• doctor.js, doctor.ps1: diagnostic tooling for both platforms.
• setup.ps1: PowerShell mirror of commands/setup.command for first-launch.
• build-icons.js: regenerates resources/icon.ico from PNGs via png-to-ico.

patches/

• node-gyp+11.5.0.patch: teaches node-gyp 11.5 about VS 2026 (Build Tools 18.5). Adds versionMajor=18 → versionYear=2026 mapping; expands [2019, 2022] arrays to [2019, 2022, 2026]; maps versionYear 2026 → toolset v145.
• node-pty+1.1.0.patch: removes Spectre-mitigated lib requirement + fixes winpty.gyp to call .\GetCommitHash.bat / .\UpdateGenVersion.bat (Windows security setting NoDefaultCurrentDirectoryInExePath=1 breaks the bare cmd /c "cd shared && GetCommitHash.bat" pattern).

src/main/

• platform/win-process.ts: NEW. Centralized Windows helpers for binary discovery (probes %APPDATA%\npm, %LOCALAPPDATA%\npm, %LOCALAPPDATA%\Programs\claude, Volta, then where claude), PATH enrichment, cmd.exe wrapping for .cmd/.bat files, and taskkill /T /F for full subprocess-tree cleanup.
• cli-env.ts, process-manager.ts, claude/run-manager.ts, claude/pty-run-manager.ts: branch on win32 to use win-process helpers.
• index.ts: Windows-specific BrowserWindow flags (thickFrame:false, paintWhenInitiallyHidden:false), Ctrl+Alt+C summon hotkey on Windows (Alt+Space collides with Windows system menu), region screenshot via desktopCapturer + ms-screenclip URI, JumpList delight item, gridWindow snap-grid for multi-monitor positioning, multi-tab Ctrl+Alt+1..9 global hotkeys, tray.ico variant on Windows.
• skills/installer.ts: replaced curl|tar shell pipeline (Windows bsdtar doesn't accept the glob arg form) with Node-native fetch + the tar npm package. Cross-platform; no shell.

src/preload/index.ts

• New exports: takeScreenshot now takes optional 'region' | 'fullscreen' mode; activate-tab-by-index event for global Ctrl+Alt+1..9 hotkeys.

src/renderer/

• ConversationView, SearchPanel, StatusBar: minor Windows-aware tweaks (CMD label, screenshot mode plumbing, terminal-launcher discovery).

src/shared/types.ts

• Channel constants for new IPC: START_WINDOW_DRAG, ACTIVATE_TAB_BY_INDEX, TAKE_SCREENSHOT mode. New TerminalInstallation/PreferredTerminalId types.

resources/

• icon.ico, tray.ico: multi-res Windows icons (16/24/32/48/64/128/256) generated from existing PNG assets via png-to-ico.

distribution/

• winget manifest (Clui.installer.yaml + .locale.en-US.yaml + .yaml): scaffolded for winget install ElecTream.Clui once first release is tagged.
• scoop bucket entry (clui.json): for users who prefer scoop.
• README.md: distribution channel overview.

.github/workflows/

• release.yml: now matrix-builds macOS arm64 + macOS x64 + windows-latest. windows-latest ships VS 2022 Build Tools preinstalled so node-pty rebuilds cleanly. --publish always uploads all artifacts to the same GitHub Release tag.
• ci.yml: NEW. Non-tag PR CI — both OSes, build only, no publish.

docs/

• WINDOWS.md: parity matrix, node-pty troubleshooting, SmartScreen workaround, hotkey rebinding, tray pinning. Living doc.
• BUBBLE_RESEARCH.md, MOBILE.md: prior-session research artifacts on potential Android bubble interface for remote Claude sessions.

README.md

• Added Windows fork callout linking to upstream + install/dev sections for both platforms.
