fix(claude): correct project encoded path (#451)

fix wrong regex replace of Claude project path

related #447, reopen due to forced-push

to reproduce error steps, let's try

Create a folder with @ in name like @test
Add this folder as new project in CloudCLI
Choose Claude tool in new Session
Star by typing sth 'hi'
In the dev tools, you will see errors ajax response said that session does not find for 'some-session-id'

The main problem is current encode path doesn't encode '@' to '-' as Claude did
I reversed code Claude-SDK, file 'cli.js' to find exactly regex (using in PR) that used to encode path under ~/.claude/projects/<encoded-project-name-path/<session-id>.jsonl

server/index.js
