feat: add bounded session and history navigation

Browse Source 
Add session scrolling, latest-message navigation and fingerprint location under the shared UI gate; reuse navigation in history reads and provide read-only smoke. Navigation index snapshot passed 124 tests and a full build. Windows 4.1.13.63 read-only validation passed 10/10, including two-scroll history location; no sends. Record scope limits, including next-unread navigation not yet implemented.
