v1.1.8

Added

• Bare-command welcome detects missing ffmpeg and ffprobe alongside chromium. Lists per-OS install hints (apt / pacman / dnf / brew / winget).
• Init wizard prints the resolved cwd and gates further prompts behind an explicit confirm before scaffolding.

Docs

• README first-demo section leads with cd <product-root> and explains why running init from a non-product directory breaks the scaffold's defaults.
• New "After installing: run the doctor first" section pointing at the system-only showrunner doctor pass.
