refactor(interactive-bash-blocker): replace regex blocking with environment configuration

Instead of blocking commands via regex pattern matching (which caused false
positives like 'startup', 'support'), now wraps all bash commands with:
- CI=true
- DEBIAN_FRONTEND=noninteractive
- GIT_TERMINAL_PROMPT=0
- stdin redirected to /dev/null

TUI programs (text editors, system monitors, etc.) are still blocked as they
require full PTY. Other interactive commands now fail naturally when stdin
is unavailable.

Closes #55 via alternative approach.
