Creates or retunes one CloakBrowser stealth identity per account under .stealth/<name>/ — rolls a unique fingerprint seed, binds a proxy after preflighting it, fixes timezone and locale coherence. Use to set up, create, reconfigure or retune a stealth identity or browser profile for an account, or change its locale or timezone. Not for installing the toolchain, or for browsing, logging in, or canary-testing a session.
