Every runtime path for an OS-supplied playlist existed, but no packaging
metadata claimed the file types — so the OS never offered IPTVnator as a
handler and `open-file` could not fire from Finder.
`fileAssociations` declares one entry per extension. Electron Builder derives
all three platform registrations from it: macOS `CFBundleDocumentTypes` (the
prerequisite for `open-file`), the NSIS registry entries, and, on Linux, the
desktop entry's `MimeType` plus `/usr/share/mime/packages/iptvnator.xml` for
deb/rpm/pacman. Neither platform needs a dedicated icon — both fall back to the
app icon.
Declaring `MimeType` under `linux.desktop.entry` would not have worked:
Electron Builder assigns the association-derived value *after* spreading that
object, so an explicit key there is silently overwritten. The per-association
`mimeType` fields produce the same entry through the supported path.
Registering the types also exposes a gap in the delivery side. The generated
Linux `Exec` ends in `%U`, so file managers hand over a percent-encoded
`file://` URI rather than a path, which `createPlaylistOpenRequest` would have
resolved into a bogus relative path. It now decodes a `file://` candidate
before the extension check. Suppressing the `%U` instead would mean putting an
exec code in `linux.executableArgs`, which also passes it to the app as a real
argument.
Verified on macOS against a signed packaged bundle: Launch Services lists the
app as a `public.m3u-playlist` handler, and an LS-initiated open imports the
playlist both on a cold launch and against the already-running process.

Adds experimental embedded MPV support for Windows and Linux, expands packaging/runtime validation, and updates CI coverage for the cross-platform native addon.
- Introduced tooling for building and staging the macOS `libmpv` runtime for IPTVnator's embedded MPV player.
- Added `build-macos-runtime.mjs` for building an LGPL-compatible runtime from source.
- Created `stage-macos-runtime.mjs` for staging the built runtime artifacts.
- Implemented validation for the packaged embedded MPV runtime in `electron-after-pack.cjs` and `embedded-mpv-macos.cjs`.
- Updated packaging scripts to ensure the embedded MPV runtime is correctly integrated and validated during the build process.
- Added README files to document the expected layout and usage for the embedded MPV runtime artifacts.

Improve sandbox handling on Linux by detecting Snap, Flatpak,
and AppImage environments and applying appropriate Chromium
command-line switches:
- If running in Snap or Flatpak, disable Chromium's sandbox
(--no-sandbox) to avoid conflicts with the distribution's
own sandboxing.
- Otherwise (traditional packages and AppImage), disable the
SUID sandbox and prefer the user namespace sandbox
(--disable-setuid-sandbox). This avoids requiring a SUID
chrome-sandbox binary and aligns with modern Linux best
practices.
Also adjust apps/electron-backend/src/main.ts to only apply
these changes on Linux (process.platform === 'linux').
Minor formatting: expand the package.json copy "filter" array
to a multiline style for readability.
