fix(ci): pin npm for publish workflow

## Summary

- add a server-backed HTTPS proxy flow for Tauri remote windows so
self-signed remote HTTPS works with the local CLI TLS assets and desktop
auth/cookie handling
- manage remote proxy sessions through `packages/server` with
per-session bootstrap, local-only cleanup, and explicit session
lifecycle handling
- support the Tauri desktop flow across environments, including packaged
Windows builds, `tauri dev`, and updated Linux/macOS handling for the
new local HTTPS proxy path

## Testing

- `npm run build --workspace @neuralnomads/codenomad`
- `cargo check`
- `npm run build --workspace @codenomad/tauri-app`
- Windows smoke test for concurrent remote proxy bootstrap sessions
- Windows manual validation of packaged Tauri remote connection flow

## Notes

- Windows was validated end-to-end.
- Linux and macOS code paths were updated for the new proxy flow, but
runtime validation on those platforms is still pending.

-### 🖥️ Desktop App (Recommended)
-The best experience. A native application (Electron-based) with global shortcuts, deeper system integration, and a dedicated window.
+Available as both Electron and Tauri builds — choose based on your preference.
 
-- **Download**: Grab the latest installer for macOS, Windows, or Linux from the [Releases Page](https://github.com/shantur/CodeNomad/releases).
-- **Run**: Install and launch like any other app.
+Download the latest installer for your platform from [Releases](https://github.com/shantur/CodeNomad/releases).
 
-### 🦀 Tauri App (Experimental)
-We are also working on a lightweight, high-performance version built with [Tauri](https://tauri.app). It is currently in active development.
-
-- **Download**: Experimental builds are available on the [Releases Page](https://github.com/shantur/CodeNomad/releases).
-- **Source**: Check out `packages/tauri-app` if you're interested in contributing.

-## Troubleshooting
+---
 
-### macOS says the app is damaged
-If macOS reports that "CodeNomad.app is damaged and can't be opened," Gatekeeper flagged the download because the app is not yet notarized. You can clear the quarantine flag after moving CodeNomad into `/Applications`:
+## Development
 
-```bash
-xattr -l /Applications/CodeNomad.app
-xattr -dr com.apple.quarantine /Applications/CodeNomad.app
-```
-
-After removing the quarantine attribute, launch the app normally. On Intel Macs you may also need to approve CodeNomad from **System Settings → Privacy & Security** the first time you run it.
-
-### Linux (Wayland + NVIDIA): Tauri AppImage closes immediately
-On some Wayland compositor + NVIDIA driver setups, WebKitGTK can fail to initialize its DMA-BUF/GBM path and the Tauri build may exit right away.
-
-Try running with one of these environment variables:
-
-```bash
-# Most reliable workaround (can reduce rendering performance)
-WEBKIT_DISABLE_DMABUF_RENDERER=1 codenomad
-
-# Alternative for some Wayland setups
-__NV_DISABLE_EXPLICIT_SYNC=1 codenomad
-```
-
-If you're running the Tauri AppImage and want the workaround applied every time, create a tiny wrapper script on your `PATH`:
-
-```bash
-#!/bin/bash
-export WEBKIT_DISABLE_DMABUF_RENDERER=1
-exec ~/.local/share/bauh/appimage/installed/codenomad/CodeNomad-Tauri-0.4.0-linux-x64.AppImage "$@"
-```

-## Architecture & Development
-
-CodeNomad is a monorepo split into specialized packages. If you want to contribute or build from source, check out the individual package documentation:
+CodeNomad is a monorepo built with:
 
 | Package | Description |
 |---------|-------------|
-| **[packages/electron-app](packages/electron-app/README.md)** | The native desktop application shell. Wraps the UI and Server. |
-| **[packages/server](packages/server/README.md)** | The core logic and CLI. Manages workspaces, proxies OpenCode, and serves the API. |
-| **[packages/ui](packages/ui/README.md)** | The SolidJS-based frontend. Fast, reactive, and beautiful. |
+| **[packages/server](packages/server/README.md)** | Core logic & CLI — workspaces, OpenCode proxy, API, auth, speech |
+| **[packages/ui](packages/ui/README.md)** | SolidJS frontend — reactive, fast, beautiful |
+| **[packages/electron-app](packages/electron-app/README.md)** | Desktop shell — process management, IPC, native dialogs |
+| **[packages/tauri-app](packages/tauri-app)** | Tauri desktop shell (experimental) |
 
-### Quick Build
-To build the Desktop App from source:
+### Quick Start
 
-1.  Clone the repo.
-2.  Run `npm install` (requires pnpm or npm 7+ for workspaces).
-3.  Run `npm run build --workspace @neuralnomads/codenomad-electron-app`.
+```bash
+git clone https://github.com/NeuralNomadsAI/CodeNomad.git
+cd CodeNomad
+npm install
+npm run dev
+```
