…er.navigation.type bfcache becomes back-forward-cache, and back-forward and restore are no longer folded into navigate. The SDK now passes the web-vitals value through verbatim, so the attribute vocabulary matches it.

web-vitals reports a navigationId of 0 when the browser does not expose PerformanceEntry.navigationId, so 0 means the id is unknown rather than being a real navigation id.

The attribute documented
bfcacheand folded a bfcache miss intonavigate, which the SDK no longer does since it passes the web-vitals value through verbatim, fixed by listing the full web-vitals vocabulary and describingback-forward-cache,back-forwardandrestoreas distinct values.Not considered a breaking change because the attribute is typed as arbitrary string and browsers can easily add new types or drift the current values.
Also fixes the doc notes for the
browser.navigation.idpossible values.
