feat: add mpv with ModernZ OSC as default video player

- mpv-modernz-git + mpv-thumbfast-git in aur.txt
- /etc/mpv/mpv.conf disables stock OSC + title bar
- /etc/mpv/script-opts/modernz.conf overrides colors to Catppuccin Mocha (lavender accent)
- moonarch-doctor checks deployed mpv configs

+## mpv + ModernZ OSC
+
+Videoplayer ist `mpv` mit [ModernZ](https://github.com/Samillion/ModernZ) als OSC, Thumbnails via thumbfast:
+- `mpv-modernz-git` liefert `modernz.lua` + Font + Default-Config nach `/etc/mpv/`
+- `mpv-thumbfast-git` liefert `thumbfast.lua` nach `/etc/mpv/scripts/` (wird von ModernZ automatisch erkannt)
+- `defaults/etc/mpv/mpv.conf` deaktiviert Stock-OSC (`osc=no`) und Titelleiste (`title-bar=no`)
+- `defaults/etc/mpv/script-opts/modernz.conf` überschreibt die Farben auf Catppuccin Mocha (Lavender als Accent, matcht waybar/swaync)
+- Deploy via moonarch-git: staging nach `/usr/share/moonarch/mpv/`, `post_install` kopiert nach `/etc/mpv/` (modernz.conf wird dabei gegenüber dem AUR-Default überschrieben — gleiches Pattern wie foot.ini/waybar style.css)

 # Decisions
 
+## 2026-04-24 – Stasis: flip `ignore_remote_media` to false for browser video
+- **Who**: Dominik, ClaudeCode
+- **Why**: Idle was firing on a second machine even while a video was playing in the browser. Original config carried the comment "browser uses D-Bus inhibit" and set `ignore_remote_media true`, deliberately excluding browser MPRIS on the assumption that Firefox/Chromium would keep the session alive via `org.freedesktop.ScreenSaver.Inhibit`. Verified against browser behavior: both browsers only raise that inhibit during **fullscreen** video playback (Firefox also requires `dom.screenwakelock.enabled`, default off on Linux). Windowed playback — the common case, YouTube in a tab — sends no inhibit, so stasis saw zero inhibitors and zero media players and ran the full idle plan to suspend. Upstream example config lists `r"firefox.*"` in `inhibit_apps` for exactly this reason; Moonarch removed it without a working substitute.
+- **Tradeoffs**: Three options. (A) Put `firefox`/`chromium` back into `inhibit_apps` — works but inhibits whenever the browser *process* is running, even with zero tabs playing; wrong shape. (B) Tell users to flip `dom.screenwakelock.enabled` per browser — pushes per-user config, fragile across browsers. (C) Let browser MPRIS count as a media player by setting `ignore_remote_media false` — stasis already tracks playback state, so it only inhibits during actual playback. Picked C. Cost: any MPRIS source stasis classifies as "remote" (e.g. a Chromecast bridge) now also inhibits; acceptable — that is usually what a user wants anyway, and the inhibit releases the moment playback stops.
+- **How**: `defaults/xdg/stasis/stasis.rune` — `ignore_remote_media true` → `false`, comment rewritten to document the fullscreen-only D-Bus behavior. PKGBUILD deploys to `/etc/xdg/stasis/stasis.rune`; existing users still need the 2026-04-22 seed mechanism (or a manual merge) to pick it up in `~/.config/stasis/stasis.rune`.

 ## 2026-04-22 – moonarch-doctor housekeeping: drop stale check, add missing services
 - **Who**: Dominik, ClaudeCode
 - **Why**: Noticed while running `moondoc` on a healthy system that it reported `Paru [moonarch-pkgbuilds] repo missing from /etc/paru.conf` — a false failure. The paru PKGBUILD-repo mechanism was retired on 2026-04-20 in favor of the registry-only flow, and the `moonarch-git` install hook strips the legacy paru.conf section on upgrade; the doctor script was not updated in lockstep. Audit of the rest of the script surfaced two related gaps: the user-services loop skipped `walker.service` and `nautilus.service`, even though the PKGBUILD ships both in `/etc/systemd/user/` and enables them via `graphical-session.target.wants` symlinks. A silently missing walker or nautilus would not show up in diagnostics.
