feat(plugins): let plugin code open streaming log tabs (#2082)

views.open-log-tab(key, title, process-log) (SDK host::open_log_tab) opens the read-only log tab a web view opens with open-log-tab, from a command or event of a window, reusing the Services pane's process-log.

The host checks the process grant and limits when called and remembers what each key runs in that window; the tab starts it by key (plugin_log_tab_spawn) through the web-view PTY checks: pinned program, trusted project, session cap, lifecycle and grant revocation. Remote windows report that these tabs aren't available there yet.
