py_func, lua_func and the run item now reach host binaries through
`flatpak-spawn --host` instead of trying to load them under the
sandbox runtime (which fails with a glibc ABI mismatch). Adds
`--talk-name=org.freedesktop.Flatpak` to the manifest, stages the
/app/lib/testium tree under /tmp so the host can read it, and drops
the dead `_FLATPAK_HOST_DIRS` / lib-injection code paths that the
new approach makes obsolete.
Validation suite gains a `--mode source|wheel|pyinstaller|flatpak|
appimage` flag so the same item set can run against every packaging
channel; per-mode report file names avoid clobbering.

The v0.1.2 fix that forced Qt's non-native dialog for the "open test"
dialog only covered one call site. The same XDG-portal-vs-sibling-files
problem applies to every other QFileDialog in the GUI (save report,
log file path, default report/log dirs in preferences, python/lua
interpreter pickers).
Extracted a single ``file_dialog.options()`` helper in main_win/ and
threaded it through every getOpenFileName / getSaveFileName /
getExistingDirectory call in main_win/. Outside Flatpak the helper
returns an empty Options(), so the native dialog stays in use on
KDE / GNOME / Windows / macOS.
