fix: prevent orphaned installer processes from blocking retries (#790)

* fix: prevent orphaned installer processes from blocking retries

When the `timeout` command expires during Claude Code installation, it only
kills the direct child bash process, not the grandchild installer processes.
These orphaned processes continue holding a lock file, causing retry attempts
to fail with "another process is currently installing Claude".

Add `--foreground` flag to run the command in a foreground process group so
all child processes are killed on timeout. Add `--kill-after=10` to send
SIGKILL if SIGTERM doesn't terminate processes within 10 seconds.
