fix(tui): blitz closeout — input wrap parity, shift-tab yolo, bottom statusline

- input wrap: add <Text wrap="wrap-char"> mode that drives wrap-ansi with
  wordWrap:false, and align cursorLayout/offsetFromPosition to that same
  boundary (w=cols, trailing-cell overflow). Word-wrap's whitespace
  reshuffle was causing the cursor to jump a word left/right on each
  keystroke near the right edge — blitz row 9
- shift-tab: toggle per-session yolo without submitting a turn (mirrors
  Claude Code's in-place dangerously-approve); slash /yolo still works
  for discoverability — blitz row 5 sub-item 11
- statusline: lift StatusRule out of ComposerPane to a new StatusRulePane
  anchored at the bottom of AppLayout, below the input — blitz row 5
  sub-item 12
