fix(terminal): start PTY before viewport mounts without dropping output or startup replies

Terminal creation no longer waits for the Ghostty viewport to report its size: it starts the PTY immediately with a container/font-derived provisional size (falling back to 80x24), then resizes once the real viewport dimensions are known, with a dedupe guard while sizing settles. Starting the shell earlier means it can emit device/theme queries before a browser terminal is attached to answer them, so the server now answers primary device attribute queries itself (Fish blocks ~10s on this at startup) and bun-pty buffers output emitted before a data subscriber attaches. Also fixes a few WebSocket transport reconnect races surfaced by session creation now overlapping renderer setup.
