Allow bundled browser plugins to run executor cleanup hooks (#40993)

## Why

Executor plugin manifests are unsigned, so cleanup hooks must remain limited to
explicitly trusted plugin identities and MCP targets.

## What changed

- Allow the bundled Browser, Chrome, Chrome Dev, and Chrome Internal plugins to
  run the existing `Stop` hook for `node_repl.turn_ended`.
- Continue allowing the bundled Computer Use plugin and rejecting unlisted or
  lookalike marketplace identities.

## Testing

- Extend manifest-filtering coverage for unlisted bundled plugins and marketplace
  name variants.
