Restore --no-session-persistence flag

Description

The --no-session-persistence flag no longer exists in the CLI but is still documented and was previously available.

Steps to Reproduce

1. Run claude --help - the flag is not listed
2. Run claude --print --no-session-persistence "test" - returns error: unknown option '--no-session-persistence'

Request

Please restore this flag. It's essential for automation scripts (pre-commit/pre-push hooks, CI pipelines) where ephemeral queries shouldn't pollute session history.

Without it, every claude --print invocation creates a session entry that clutters the --resume picker.

Environment
