v1.3.52 - Test combined navigation recovery

I added a bounded example that combines navigation, unsaved edits and session recovery in one lifecycle. Departure choices bind the exact destination and revision; old acknowledgements cannot release another departure or certify newer work. Owner/resource/session checks keep late effects scoped, while unknown writes and changed remote versions stop replay.

The portable navigation, unsaved-edit and session guides now describe composition precedence and its evidence requirements. The independent examples and installer/updater compatibility contracts remain unchanged.

Validation includes 189 literal state/effect checkpoints in 20 sequences, 22 faulty variants passing ordinary controls first, 34 focused tests, 885 source and extracted-package tests, eight disposable client/integration upgrades and non-author review. Linux CI retains three existing skips per suite; Windows/macOS have none.

This is a same-author, source-exposed synthetic proposed policy. It establishes no real browser history, authentication, service authorization, secure/durable storage, original-app parity or model quality. Unknown outcomes and version conflicts remain explicit stops without automatic reconciliation. Installed-file verification does not establish host instruction reload.
