INCIDENT: user installed via curl|bash and reported "kei did not auto-launch".
Root cause: under curl|bash, stdin is the pipe from curl. Every interactive
gate `[ -t 0 ]` returned FALSE, silently skipping FIVE places:

  install/lib-i18n.sh         language picker
  install/lib-preflight.sh    preflight checks
  install/lib-hooks.sh        hook activation prompt
  install/lib-wizard.sh       sleep wizard
  install.sh:270              PATH wiring
  bootstrap.sh kei-onboard    primary CLI picker
  bootstrap.sh launch prompt  "запустить kei сейчас?"

Per rules/tty-interactivity-gate.md the rule is "gate on stdin, never stdout"
— and we did. But under curl|bash BOTH are non-tty. /dev/tty is the only
reliable signal that the user is interactive.

FIX: in bootstrap.sh, ONCE, before invoking install.sh:

    if [ -r /dev/tty ] && [ -w /dev/tty ]; then
        exec </dev/tty
    fi

This redirects bootstrap.sh's OWN stdin to /dev/tty. Every child process
inherits it via fork — install.sh, lib-*.sh, kei-onboard.sh, kei-pick.sh,
kei-mcp-wire.sh — and their `[ -t 0 ]` gates now correctly report true.
Headless / CI / nohup (no /dev/tty) → skipped, gates stay false, no prompts.

Simplified the v0.47 onboarding + launch-prompt blocks: they no longer
need have_tty() or explicit </dev/tty redirects on read — the global
reattach handles it cascadally.

Smoke-tested 2 of 3 paths (curl|bash via `echo "" | bash script.sh` ✓;
plain bash needs real TTY which Claude Code sandbox doesn't provide;
headless needs setsid which is Linux-only). Logic verified.

Version bump v0.47 → v0.48 because behaviour materially changes for every
curl|bash user (5 prompts now fire that were silently skipped).
