- renamed getSelectedPage to getSelectedPptrPage
- removes getSelectedPptrPage from tool interfaces
- moves dialog handling to McpPage
- makes responses to be optionally McpPage-scoped
## Summary
Adds optional `pageId` routing to page-scoped tools, gated behind
`--experimental-page-id-routing`. When enabled, multi-agent callers can
target a specific page without relying on global selection state. Fully
backward-compatible: without the flag, behavior is unchanged.
### Key changes
- **`pageScoped` annotation**: tools declare `pageScoped: true`; the
server merges `pageId` into their schema at registration time (when the
flag is on)
- **`McpPage` wrapper**: consolidates per-page state (numeric id,
isolated context name, focus tracking) into a single class
- **Request-scoped page routing**: `resolvePageById()` resolves the
target page, `setRequestPage()` threads it through the handler so tools
like `getSelectedPage()` see the right page
- **`assertPageIsFocused`**: keyboard/input tools validate that the
target page holds browser focus, returning an actionable error ("call
select_page first") instead of silently dispatching to the wrong page
- **`--experimental-page-id-routing` CLI flag** (hidden): gates schema
injection and request-scoped routing so the feature can be tested before
graduating
- **Eval scenarios**: `page_id_routing_test` and
`page_focus_keyboard_test` with `serverArgs` support in the eval harness
Addresses #1019
previously, Chrome DevTools MCP was strictly requiring the client to use
the latest snapshot. This change updates the behavior to be more
lenient. Previously issued uids will be recognized if the underlying
backend Id (loaderId + backendNodeId) still exists.

I split this PR off from my "create one DevTools universe per page" PR
in preparation. This allows tests to re-use browser instances without
creating an `McpContext`.
Drive-by: Move mocked browser/page into utils.ts.
This PR prevents license notices being dropped when creating package for
publication.
This can happen when first import in the file is type-only import that
gets removed during build. When there is no empty line between the
license block comment and such import, the comment is treated as related
to the import and gets removed alongside it.
Adding an empty line between copyright notice and the import fixes the
issue.
