fix(share): terminal access for late joiners, auto-scroll, inventory scroll

- A guest who joined after the host enabled the terminal stayed read-only; the
  host now re-sends the terminal state on join (req_full), so the terminal works.
- The shared terminal follows the cursor to the bottom as output arrives (ls -la)
  instead of staying scrolled up.
- The Inventory page preserves scroll position on refresh (and skips re-rendering
  unchanged data), so it no longer jumps to the top while you're reading.

+## [0.7.1] - 2026-05-21
+### Fixed
+- Shared terminal: a guest who joined **after** the host enabled the terminal stayed read-only.
+  The host now re-sends the terminal state when a guest joins, so the terminal is available.
+- Inventory page no longer jumps back to the top when it refreshes (e.g. when elevated data
+  arrives) — scroll position is preserved and unchanged data isn't re-rendered.
+- Shared terminal now follows the cursor to the bottom as output arrives (e.g. `ls -la`),
+  instead of staying scrolled up.
+
 ## [0.7.0] - 2026-05-21
 ### Added
 - **Shared terminal (M12, Tier 3)**: when the host enables it, the session shares a real **PTY**
