Introduce a full codex-tui source snapshot under the new codex-tui2 crate so viewport work can be replayed in isolation. This change copies the entire codex-rs/tui/src tree into codex-rs/tui2/src in one atomic step, rather than piecemeal, to keep future diffs vs the original viewport bookmark easy to reason about. The goal is for codex-tui2 to render identically to the existing TUI behind the `features.tui2` flag while we gradually port the viewport/history commits from the joshka/viewport bookmark onto this forked tree. While on this baseline change, we also ran the codex-tui2 snapshot test suite and accepted all insta snapshots for the new crate, so the snapshot files now use the codex-tui2 naming scheme and encode the unmodified legacy TUI behavior. This keeps later viewport commits focused on intentional behavior changes (and their snapshots) rather than on mechanical snapshot renames.
