Added experimental_devProcessCwdInBuildDir config option (#2269)

* Added experimental_devProcessCwdInBuildDir config option

Added experimental_devProcessCwdInBuildDir config option to opt-in to new process.cwd behavior when executing tasks in the dev CLI. Currently process.cwd maps to the "root" of your trigger.dev project (the directory that contains your trigger.config.ts file). Setting experimental_devProcessCwdInBuildDir to true changes process.cwd to instead be the temporary build directory inside of the .trigger directory.

This makes it so the files added via the additionalFiles extension can be read using the same path in dev and deployed tasks.

* Remove claude code reference because it breaks windows tests 😡
