Spawn `claude` directly as the tmux command with
CLAUDE_CODE_NO_FLICKER=1 so Claude Code runs in its fullscreen TUI
mode (input box pinned at bottom, owns its own scrollback). Mouse
wheel events are converted to PgUp/PgDown key input — universal
scroll signal that Claude, less, vim normal mode all respect, and
sidesteps the mouse-mode-but-no-scroll dead end where TUI apps
capture mouse without binding the wheel.
Drops the 1000-row tmux canvas + SingleChildScrollView experiment
in favor of viewport-sized tmux and Claude's native bottom-pinning.
Makefile install target now kills the clide tmux server so the
new config takes effect immediately. Marked TEMP — to be removed
once we no longer need the rapid-iteration loop.
