When no install-state is found for the current context, `ecc uninstall`
now checks for the legacy `sync-ecc-to-codex.sh` ownership manifest under
`~/.codex/ecc/legacy-sync-state.json` and, if present, rolls back the
managed Codex artifacts it recorded. It restores previous `config.toml`
and `AGENTS.md` content instead of deleting them, removes generated
prompts/docs/copies, and leaves unrelated Codex conversation history and
user config keys untouched. A fallback `--legacy-codex-sync` flag still
forces the legacy path explicitly, and `--dry-run` previews the cleanup.
