## Title

    [Claude Code install] 'Raw mode is not supported' when installing via curl | bash with org managed settings needing approval

## Body

    Cause (Documented platform behavior): Approval dialog needs a TTY on stdin.
    
    Fix status: released_fix (fixed in 2.1.246)
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://code.claude.com/docs/en/troubleshoot-install (official_docs, 2026-09, released_fix): Docs explain the pipe-stdin cause and that 2.1.246+ defers the dialog, except with fail-closed settings fetch.
    
    Search phrasings: claude code install raw mode is not supported; ink raw mode not supported stdin pipe claude
    
    Evidence basis (self-declared by the contributing chat client): public_source.
