What's Wrong?

This is related to some existing reports, like #9670 but that is more about capturing too much stuff for the shell snapshot. (My snapshots are ~30k lines, too... that's 757k)

But even more it is related to #1872 because I keep getting the same kind of `.claude/shell-snapshots/snapshot-zsh-1768565670194-de9c7g.sh:15362: parse error near ()'`` issue.

In that issue, someone blamed the zsh plugin. However, by checking the line in the plugin file in my .oh-my-zsh/lib/functions.zsh I see this:

local mark='_.!~*''()-'

Whereas the claude snapshot has:

local mark='_.!~*'()-'

I suspect this is some sort of issue caused by setopt rcquotes (it's a zsh option that makes it possible to do echo 'don''t' and get don't)

What Should Happen?

I would expect if you capture the entire shell environment based on the user's own interactive shell, it should work even if people have some helper options set.

Steps to Reproduce

1. Use zsh
2. Install oh-my-zsh
3. Add setopt rcquotes to .zshrc
4. Run any shell command in claude

Additional Information

For now, I got around it by doing this in my .zshrc

if [[ -z "${CLAUDECODE}" ]]; then
  setopt rcquotes
fi

After that, the snapshots seem to have the correct line:

local mark='_.!~*''()-'
