M0 scaffold — Python addon + Rust sidecar

Kodi addon (plugin.video.torttube) shell with Cargo workspace for the
rustypipe-backed sidecar binary. No working extraction yet — addon.xml
parses, main.py is a notification stub, sidecar's main.rs prints scaffold
banner. See MILESTONES.md for M1..M6.

License: GPL-3.0-or-later (matches rustypipe + NewPipeExtractor).
