VoipAppz Builder 0.1.15

Windows installer: VoipAppz.Builder_0.1.15_x64-setup.exe. Not code-signed yet, so SmartScreen warns on first open (More info → Run anyway). On Windows, choose a voipappz/app checkout inside WSL2 (\\wsl.localhost\<distro>\…).

Changes since v0.1.9:

• Builder opens in its own window (WebView2) instead of the default browser; the tray has Open in Browser.
• The setup window shows the API login as green once it is set, and the version in the header and tray.
• Pre-flight checks the API login before setup; a login saved in the app checkout's .env is used for Builder's worktree.
• The setup sign-in uses the API address you chose.
• The agent runs from the app's own packages (bin/npm.sh exec -- claude-agent-acp), npx until the app has it.
• Setup errors include the app's own explanation.
• CI: an end-to-end job clones voipappz/app and runs setup, dev, Builder and the agent.
