feat(browse): BrowserManager deviceScaleFactor + setContent replay + file:// plumbing
Three tightly-coupled changes to BrowserManager, all in service of the
Puppeteer-parity workflow:

1. deviceScaleFactor + currentViewport tracking. New private fields (default
   scale=1, viewport=1280x720) + setDeviceScaleFactor(scale, w, h) method.
   deviceScaleFactor is a context-level Playwright option — changing it
   requires recreateContext(). The method validates (finite number, 1-3 cap,
   headed-mode rejected), stores new values, calls recreateContext(), and
   rolls back the fields on failure so a bad call doesn't leave inconsistent
   state. Context options at all three sites (launch, recreate happy path,
   recreate fallback) now honor the stored values instead of hardcoding
   1280x720.

2. BrowserState.loadedHtml + loadedHtmlWaitUntil. saveState captures per-tab
   loadedHtml from the session; restoreState replays it via newSession.
   setTabContent() — NOT bare page.setContent() — so TabSession.loadedHtml
   is rehydrated and survives *subsequent* scale changes. In-memory only,
   never persisted to disk (HTML may contain secrets or customer data).

3. newTab + restoreState now consume validateNavigationUrl's normalized
   return value. file://./x, file://~/x, and bare-segment forms now take
   effect at every navigation site, not just the top-level goto command.

Together these enable: load-html → viewport --scale 2 → viewport --scale 1.5
→ screenshot, with content surviving both context recreations. Codex v2 P0
flagged that bare page.setContent in restoreState would lose content on the
second scale change — this commit implements the rehydration path.

return value), plan Feature 3 + Feature 4.
