Merge branch 'feat/v070-altv' (#138 Alt+V chord for tool-details pager)

- crates/tui/src/tui/ui.rs — new Alt+V/Alt+Shift+V arm next to Alt+A/Y/P family, no empty-input gate
- crates/tui/src/tui/history.rs — 5 hint strings + 4 test assertions updated to "Alt+V for details"
- crates/tui/src/tui/keybindings.rs — entry under Submission so ? overlay lists it
- Bare 'v' handler unchanged (legacy muscle memory)
