description: Update claude-carbon to the latest version and re-price history (CO2-only)

Run the following bash script exactly as written and present its output to the user. Do not paraphrase. It updates the user's claude-carbon install (dirty-safe `git pull`), refreshes setup, and re-prices stored sessions with the new factors.

#!/usr/bin/env bash
# Locate the install that is actually wired into the status line, then run its updater.

# Windows (Git Bash): CLAUDE_* variables and the paths stored in settings.json can
# arrive in the native "C:\Users\..." spelling, which bash cannot open. cygpath
# ships with Git for Windows; everywhere else this is the identity function.
