User reports launch crashing only inside tmux (works outside).
The wrapper itself runs fine in standalone tmux repros, so the
break is in some interaction we can't see — curses eats stderr,
default tmux remain-on-exit is off, and the pane closes before
the operator can read anything.
Add an always-on per-pid log at ~/.claude-bottle/pty_resize.log:
- start record: argv, cwd, PATH, TMUX status
- sync record: window size observed
- child pid + exit rc
- any KeyboardInterrupt forwarding
- Popen failure traceback if it dies
Append-mode, small overhead, easy to grep + share.
Removable (along with the wrapper itself) once smolvm forwards
SIGWINCH natively.
