Two issues prevented Claude from spawning in certain environments:
1. node-pty's spawn-helper binary loses execute permission during npm
install, causing posix_spawnp to fail on every PTY spawn. Fixed by
adding chmod in postinstall.
2. When Claudeman is launched from within a Claude Code session, the
CLAUDECODE env var leaks into child processes, causing Claude CLI
to refuse to start ("cannot be launched inside another Claude Code
session"). Fixed by unsetting CLAUDECODE in both tmux and direct
PTY spawn paths.
