asar 1.9659.2 calls app.configureWebAuthn() during main-process init. This is a macOS-only Electron API; on Linux Electron it does not exist, causing an uncaught TypeError that crashes the app before any window opens. Add 'configureWebAuthn' to the _macOnlyAppMethods no-op list alongside the existing NSUserActivity / Handoff stubs (issues johnzfitch#104, johnzfitch#106).

Bumps LAST_TESTED_ASAR_VERSION to 1.9659.2. Status is PARTIAL: app launches and cowork rails engage once app.configureWebAuthn is stubbed (PR johnzfitch#130), but full feature exercise (login, sessions, MCP) is pending. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Newer Claude Desktop asar versions call app.configureWebAuthn() during main-process init. We spoof process.platform=darwin, so this darwin-gated callsite fires on Linux, where Electron has no such method -- it throws TypeError and crashes the app before any window opens. Add it to the existing _macOnlyAppMethods no-op loop alongside the Handoff/NSUserActivity stubs (same root cause as johnzfitch#104/johnzfitch#106). The typeof guard means we only fill the gap when the method is absent, so a platform with a real implementation is never clobbered. Closes johnzfitch#128. Supersedes the two-file approach in johnzfitch#129 and the COMPAT version bump in johnzfitch#130; this is the minimal single-line fix. https://claude.ai/code/session_01LxAaF3raqdkyZyTPHBG8f4

Problem
asar v1.9659.2 calls during main-process initialisation. This is a macOS-only Electron API — on Linux Electron it does not exist, causing an uncaught that crashes the app before any window opens:
Fix
Add to the no-op list in , alongside the existing NSUserActivity / Handoff stubs (issues #104, #106). The method is stubbed to a no-op so the app continues without WebAuthn hardware-key support (not relevant on Linux).
