test: sidebar agent test suite (layers 1-2)
Layer 1 (unit): 18 tests for URL sanitization in sidebar-utils.ts — http/https pass, chrome:// rejected, javascript: rejected, control chars stripped, truncation. Layer 2 (integration): 13 tests for server HTTP endpoints — auth, sidebar-command queue writes, activeTabUrl override/fallback, event relay to chat buffer, message queuing, queue overflow (429), chat clear, agent kill. Source changes for testability: - Extract sanitizeExtensionUrl() to browse/src/sidebar-utils.ts - Add BROWSE_HEADLESS_SKIP env var to skip browser launch in HTTP-only tests - Add SIDEBAR_QUEUE_PATH env var to both server.ts and sidebar-agent.ts - Add SIDEBAR_AGENT_TIMEOUT env var to sidebar-agent.ts - Sync package.json version to match VERSION (0.12.2.0) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
