Module tui 

anchor debugger TUI.

Two screens drive the whole experience:

• [Screen::Picker] — startup. Lists every captured (test, tx) pair with total CU; user picks one to step into. Also reachable from the stepper via t, so jumping across txs within a session is one keypress.
• [Screen::Stepper] — foundry-style instruction stepper with panes for the instruction list, registers, call stack, and source.

Keybinds mirror forge test --debug where it makes sense:

j / k / ↑ / ↓       step ± 1 instruction
s / a               step over next/prev call
c / C               previous / next CPI invocation
g / G               first / last step in current node
t                   return to tx picker (or select in picker)
K / J               scroll call stack
q                   quit
10k                 repeat count (e.g. move up 10 steps)

Functions
