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).

+
+## M0 — Scaffold [current]
+
+- [x] `Sulkta-Coop/torttube` on LAN Gitea
+- [x] Layout: `addon/` (Python) + `sidecar/` (Rust workspace)
+- [x] GPL-3.0 license headers
+- [ ] crafting-table build target produces a static aarch64 sidecar binary
+
+## M1 — sidecar resolve
+
+- [ ] reads `{"op":"resolve","id":"<yt-id>"}` from stdin
+- [ ] calls rustypipe → returns `{"streams":[…],"title":"…","duration_s":N}`
+- [ ] handles age-restricted + region-restricted as typed errors, not panics
+- [ ] sig decoding verified against a known-good video
+- [ ] DASH manifest URL or per-itag direct stream URL — whichever inputstream.adaptive prefers
+
+## M2 — SponsorBlock
+
+- [ ] `{"op":"sponsorblock","id":"<yt-id>"}` → segments array
+- [ ] SHA-256 prefix lookup (privacy-preserving — only send first 4 hex chars)
+- [ ] category filter honoured from addon settings (skip / mute / show only)
+- [ ] cache per-session
+
+## M3 — Kodi addon plays one video
+
+- [ ] `addon.xml` + `main.py` register as video plugin
+- [ ] hardcoded list of 3 test videos
+- [ ] select → sidecar `resolve` → stream URL → Kodi player
+- [ ] verified end-to-end on LibreELEC RPi at `192.168.0.158`
+
+## M4 — search + channel browse
+
+- [ ] search box → sidecar `{"op":"search","q":"…"}` → results
+- [ ] channel browse → `{"op":"channel","id":"…"}`
+- [ ] playlist browse → `{"op":"playlist","id":"…"}`
+- [ ] result thumbnails + duration + uploader
+
+## M5 — SponsorBlock skipping
+
+- [ ] background thread on `Player()` polls position
+- [ ] when position enters a skip segment → `xbmc.Player().seekTime(end)`
+- [ ] toast on skip + skip-counter in settings
+- [ ] category toggles in `settings.xml`
+
+## M6 — install + cross-compile
+
+- [ ] crafting-table builds `torttube-sidecar.aarch64` + `.armv7`
+- [ ] `addon.zip` ships with platform detect via `xbmc.getCondVisibility('system.platform.linux.raspberrypi')`
+- [ ] one-shot install path documented for LibreELEC `/storage/.kodi/`
+
+## Upstream PR targets (parallel, opportunistic)
+
+Pick one as we hit it organically — don't gate milestones on these.
+
+- NPE #1357 (JDoc) — smallest, just to land a credible PR
+- NPE #1444 (typed errors) — clean signal/contract change
+- rustypipe — file issues + PRs on codeberg as we hit gaps
