Unreleased

Opt-in sessionId multiplexing: CDPEx.new_page(browser, transport: :session) drives many pages over the one browser WebSocket (default :dedicated = one socket per page). CDPEx.Connection.call/5 and await_event/4 gain a :session_id option.
CDPEx.Page.wait_for_navigation/2 — await a navigation lifecycle milestone without issuing a navigation (e.g. after a click that navigates).
CDPEx.Page.wait_for_function/3 — poll a JavaScript expression until it is truthy.
CDPEx.Page.text/3, attribute/4, visible?/3 — element text / attribute / visibility helpers.
CDPEx.Page.cookies/2, set_cookies/3, clear_cookies/2 — cookie get / set / clear (lazily enables the Network domain).
CDPEx.Page.set_extra_headers/3, set_user_agent/3 — extra HTTP headers and User-Agent override.
CDPEx.Page.set_viewport/4 — viewport / device-metrics emulation.
CDPEx.Page.pdf/2 — render the page to PDF (Page.printToPDF); returns bytes or writes to :path.
CDPEx.Page.call_function/4 — call a JS function with JSON-serialized arguments.

A clean browser-connection close (its socket dropping, e.g. Chrome exiting) now stops CDPEx.Browser with a :shutdown reason rather than a crash reason — no spurious error report on expected teardown. Abnormal connection failures still surface loudly.

CDPEx.Connection.call/5 and await_event/4 no longer crash the connection when given an :infinity timeout (which is valid per the timeout() spec).
CDPEx.Connection now stops when its owning process exits, closing the socket even if the owner skipped its own teardown (e.g. a :brutal_kill).

Initial OTP-native Chrome DevTools Protocol client.
CDPEx.launch/1 and CDPEx.stop/1 — supervised headless Chrome lifecycle.
CDPEx.new_page/2, CDPEx.close_page/2, CDPEx.with_page/3.
CDPEx.Page: navigate/3, wait_for_selector/3, evaluate/3, click/3, html/2, screenshot/2.
