/**
 * `summarize_console_errors` (batch-14 composite, fka `fix_console_errors` in
 * cross-review v2.0.1 — renamed because the tool surfaces signals; "fixing" is
 * LLM-side work).
 *
 * Reads `PageSession.consoleBuffer` directly (already populated by the
 * `Console.messageAdded` + `Runtime.exceptionThrown` subscribers in
 * `PageSession.init`), filters to warning/error level, groups by message
 * similarity (first 80 chars of `text` + url:line), returns top-N groups by
 * frequency with one stack trace each.
 *
 * Useful when the AI agent asks "what's broken here?" — saves it from paging
 * through `list_console_messages` + N × `get_console_message`.
