Fix runtime PRIMITIVES for dom/browser library functions

dom.sx and browser.sx are library source (not transpiled into the bundle),
so their functions need explicit PRIMITIVES registration for runtime-eval'd
SX code (islands, data-init scripts). Restore registrations for all dom/
browser functions used at runtime. Revert bootstrap.py transpilation of
dom-lib/browser-lib which overrode native platform implementations that
have essential runtime integration (cekCall wrapping, post-render hooks).

Add Playwright regression test for [object Object] nav link issue.
Replace console-log calls with log-info in init-client.sx.txt.
