Add Cytracon Omarchy apps: catsync, cctv-lite, syscare, tilix-cytracon

[cytracon]

What

Add four local packages for Cytracon apps already used on Omarchy via omarchy install … (user-local ~/.local). These PKGBUILDs install system-wide so they can appear in the official Omarchy package repository and therefore on omarchyapps.com.

Package	Version	Upstream	What it is
catsync	0.5.0	https://github.com/cytracon/catsync	Google Drive sync daemon + tray. MIT.
cctv-lite	0.2.0	https://github.com/cytracon/cctv-lite	Live RTSP camera grid. MIT.
syscare	0.3.1	https://github.com/cytracon/syscare	System optimizer (caches, updates, processes, security). MIT.
tilix-cytracon	1.9.8.cytracon.12	https://github.com/cytracon/tilix	Cytracon Tilix fork (tiling terminal, bookmarks, AI CLIs). MPL-2.0. provides/conflicts: tilix.

Matching bar plugins are already listed in the plugin marketplace (io.github.cytracon.*).

Source / updates

• Python apps: source: local with git_tags v{pkgver} from the GitHub repos.
• Tilix: source: local only. Upstream tags are v1.9.8-cytracon.N, which cannot be used as an Arch pkgver (hyphen). Mapped to 1.9.8.cytracon.12.
• Tagged GitHub releases exist for each version in this PR.

Packaging notes

• Python apps are arch=('any'). Payload under /usr/lib/<name>/, launchers in /usr/bin. User config stays in ~/.config/ and is not overwritten.
• Catsync ships user systemd units with ExecStart=/usr/bin/catsyncd daemon (not ~/.local).
• Catsync needs Google OAuth on the machine (~/.config/catsyncd/). No secrets in the package.
• CCTV Lite stores camera URLs in ~/.config/cctv-lite/ (not packaged).
• Tilix is a compiled D/GTK app. PKGBUILD prefers meson+ldc (Arch extra style) and falls back to dub if meson is not used.

Tested

• package() smoke-tested for catsync, cctv-lite, and syscare: wrappers, desktop files, icons, licenses, systemd unit paths, and python3 -m imports.
• Tilix was not compiled in this checkout (ldc/meson build belongs on the package builder).
• aarch64 for Tilix is declared but not built here.

I am the upstream maintainer (cytracon). Happy to split into four PRs if you prefer.
