What happened?
I have a very large session file (+600MB) that I have a /goal running for days there, but for some reason I had to stop it to update my pi to latest version and when I tried to open it, it crashes with the following error: Error: Cannot create a string longer than 0x1fffffe8 characters
Full stacktrace:
$ pi -c
node:fs:440
return binding.readFileUtf8(path, stringToFlags(options.flag));
^

Node.js v24.12.0Steps to reproduce
That is a bit tricky, because you have to generate a 512+ MB Session file or at least the 0x1fffffe8 characters file! and try to open it, that is a limitation in Nodejs I assume? I have to dig more.
Expected behavior
I expect it to load the file, or at least we chunk it? since it is a JSONL after all, right? maybe we lazy load older entries? I know, large session files are uncommon, but I leave my agent running sometimes 24/7 on tasks that I throw at it. Happy to make a new PR.
