feat: add comprehensive E2E test suite for desktop app

[aj47]

Add ~370 tests across 16 test suites using Electron MCP/CDP approach:

• Core: app lifecycle, navigation, IPC procedures
• Sessions: agent sessions, session lifecycle
• MCP: tool discovery, server status, elicitation/sampling
• UI: components, settings pages
• Features: conversations, message queue, profiles
• Quality: error handling, performance, integration workflows

Tests execute via electron_execute MCP tool with direct renderer access.

🤖 Augment PR Summary

Summary: Adds a large end-to-end test suite for the SpeakMCP Electron desktop app, executed via the electron-native MCP server using Chrome DevTools Protocol (CDP).

Changes:

• Introduces a new apps/desktop/e2e-tests/ directory with ~370 tests across 16 suites (core, sessions, MCP, UI, features, error handling, performance, and integration workflows).
• Adds a lightweight in-renderer test framework (utils/test-framework.ts) with assertions and helper utilities (DOM, navigation, IPC invoke).
• Adds suite aggregation and exports (index.ts) plus a code generator/runner (run-tests.ts) to produce electron_execute-ready scripts.
• Documents usage and suite coverage via README.md and IMPLEMENTATION_STATUS.md.

Technical Notes: Tests run directly in the renderer process and validate functionality primarily through window.electron.ipcRenderer.invoke() calls and DOM inspection, with suite runners evaluating test snippets dynamically.

assertionsCode/helpersCode are pre-escaped for inclusion inside a template literal (they contain sequences like \\\`` / \${...}), but generateQuickTest()inlines them directly into executable JS here. That likely produces invalid JS (stray` before template literals) and would also make the README’s generateQuickTest example fail at runtime.
