1. CRASH on word input (e.g. "claude") at any menu: $((ans-1)) under set -u →
"unbound variable" → install died. Added _onb_read_choice validation (all 4 menus).
2. Claude Code default: added claude-code subscription provider (kei-registries
submodule c559065→b904993), subscription default transport, claude-code default
provider — Enter,Enter,Enter → Claude Code, no API key.
3. install died at line 178 for no-key providers (claude-code/codex/local):
onboarding_run ended on a false `&&` → returned 1 → set -e. Added `return 0`.
Plus en+ru explanations and auto-select single-option steps. Verified piped-under-pty.
