- Split NO_TABS_ERROR into EXTENSION_NOT_CONNECTED_ERROR and NO_TABS_ENABLED_ERROR
- Add checkExtensionStatus() to detect extension state before connecting
- Provide actionable guidance in error messages
- Add -e/--eval flag to execute JavaScript code via relay server
- Extract PlaywrightExecutor class to shared executor.ts module
- Extract relay server utilities to relay-client.ts
- Add /cli/execute, /cli/reset, /cli/sessions endpoints
- Fix CDP session client ID collision by using fresh unique URLs for each connection
- Server rejects new extension (code 4002) if existing has active tabs
- Idle extensions (no tabs) can still be replaced
- Extension properly enters polling mode when rejected during handshake
- /extension/status now returns activeTargets count for smarter reconnection
* fix: add CORS middleware to allow extension connection
* fix(cors): validate extension ID to prevent other extensions from accessing endpoints

Fixes#22
CDP's Network.enable buffers response bodies by default, which breaks
SSE/streaming - data arrives at Chrome but ReadableStream never receives it.
Changes:
- Intercept Network.enable in relay, default maxTotalBufferSize: 0
- Agents can re-enable buffering via Network.disable + Network.enable
with explicit buffer sizes when they need response.body()
- Added test and documentation for reading response bodies
- Use 127.0.0.1 instead of localhost to avoid DNS/IPv6 resolution issues
- Add 15s global timeout wrapper around connect() to prevent hanging forever
- Reduce HTTP retry attempts from 30 to 5 (maintainLoop retries anyway)
- Fix WebSocket cleanup: close socket on timeout to prevent orphaned connections
- Improve settled state tracking in WebSocket connection promise
Standard Chrome DevTools Protocol HTTP discovery endpoints that allow
tools like Playwright to connect using just the HTTP URL.
- /json/version returns browser info and webSocketDebuggerUrl
- /json/list returns array of connected targets
- Supports GET/PUT methods and trailing slashes for compatibility
