Pull request overview

This PR updates the Breadcrumbs component to use Angular signal-based queries/computations to prevent a visible “reflow” during initial render (previously caused by maxWidth being null on the first CD cycle), and re-enables the previously skipped E2E suite after addressing keyboard focus ordering.

Changes:

Migrated breadcrumb item/template/query handling to signal-based APIs (contentChild, contentChildren, viewChild, viewChildren, computed, effect).
Adjusted overflow rendering to use signal reads in the template and added CSS to hide projected <kbq-breadcrumb-item> nodes.
Added unit tests for roving-focus ordering and un-skipped the Playwright suite for KbqBreadcrumbsModule.
