- Removed run-scoped Puppeteer request handlers and disabled interception on every browser.run exit path.
- Recycled workers when bounded interception cleanup cannot restore the tab, with raw CDP recovery for held requests.
- Added live Chromium coverage for held requests, normal traffic restoration, and thrown setup calls.
Fixes#6004
- Implemented cell budget clamping for timeouts to prevent stalled browser operations from exceeding execution limits.
- Added `recover` capabilities for tab workers to clear blocking dialogs and safely terminate hung navigations.
- Introduced `//!world=main` support for `tab.evaluate` via Puppeteer patch to allow execution in main execution contexts.
- Improved failure attribution for tab terminations by tracking dialogs, stalled operations, and specific termination reasons.
- Added `markHandled` helper to prevent unhandled promise rejections in fire-and-forget browser tasks.
- Integrated `postmortem.markExpectedCleanupError` to distinguish between expected teardown aborts and actual runtime failures.
- Updated `runCmuxCode` and `WorkerCore` to propagate abort reasons via `ToolAbortError` cause chains.
- Modified `tab-protocol` and supervisor logic to signal expected cleanup states during tab release.
- Added test coverage for `ToolAbortError` wrapping and cause preservation.
- Added a unified eval framework with parser grammar, backend interfaces, and JS/Python execution result types.
- Added eval tool docs and updated prompts for fenced cells, `eval.py`/`eval.js`, and fallback behavior.
- Replaced the built-in `python` tool with `eval` across registry, rendering, interactive modes, and tool settings.
- Migrated Python execution runtime from `src/ipy` to `src/eval/py`, renamed state fields, and removed legacy introspection.
- Refactored browser tooling from in-process VM helpers to worker-managed tab supervisors and protocol transport.
- Added eval parser fallback and JS tool-bridge tests, updated imports, and removed obsolete python-mode suites.
