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.
A plugin web view can open a read-only editor tab that streams a process's output, with plugin-defined toggles, Find, wrap, zoom and Clear. The process is authorised in the backend against the exact granted `process:<program>` and its pinned executable, output is bounded, and the stream survives tab switches but ends when the tab closes, the plugin is disabled or the window closes. Adds a web-log test fixture and docs. Verified on macOS; Windows/Linux not run.
