feat(tui-go): transcript message-jump + OSC52 copy

Browse Source 
ctrl+↑/↓ jumps between your sent (user) messages in the transcript: ctrl+↑ from the
bottom selects the most recent, steps to older ones (clamping); ctrl+↓ steps back and
drops to tail-follow past the last. The selected message is highlighted and scrolled
into view (routerRows tracks per-message row offsets and windows to the selection).

`y` yanks the selected message — or the latest turn when none is selected — to the
system clipboard over OSC52 (go-osc52, tmux-wrapped under $TMUX), which is SSH/Termius-
safe unlike a mouse drag. A brief "✓ copied" footer note animates out (and self-stops
the tick). esc drops the selection; switching sessions clears it. Tests cover the
user-message jump/clamp/tail and the copy-text selection.
