Chrome 144+ allows enabling remote debugging from chrome://inspect without any command-line flags (--remote-debugging-port). Chrome writes the active port and browser GUID to a DevToolsActivePort file in the user data directory. This change reads that file to auto-discover the CDP WebSocket endpoint, eliminating the need for the Playwright MCP Bridge browser extension in most cases. Connection priority: 1. OPENCLI_CDP_ENDPOINT env var (manual override) 2. DevToolsActivePort auto-discovery (Chrome/Edge, cross-platform) 3. --extension mode fallback (original behavior) Supports Windows, macOS, and Linux with Chrome, Edge, and Chromium.

P0 Critical: - #1 Fix double IIFE wrapping: unified wrapForEval() replaces normalizeEvaluateSource + ad-hoc wrap in page.evaluate() - #2 Fix navigate race: check tab.status before addListener, reduced timeout 30s→15s P1 Should Fix: - #8 Remove unused permissions (scripting, host_permissions, content_scripts) - #10 Add retry (3x, 500ms) + timeout (30s) to sendCommand() P2 Cleanup: - #3 Extract isWebUrl() to safely handle undefined tab.url - #4 Sanitize maxDepth with Math.max/min bounds - #6 Delete empty src/daemon/ directory - #7 Remove dead createJsonRpcRequest + its test - #9 Remove stale IIFE-mode comment - #11 Validate body.id in daemon request handler - #12 Guard ensureAttached: detach+re-attach on 'already attached' - #14 Extract _tabOpt() helper (removes 13x spread duplication) - #15 Add verbose warning for unsupported consoleMessages() All 35 unit tests pass.
