Completes the move: `linux/` is gone, replaced by the web build served by the
wrapper in a Chrome `--app` window. The icons and the .desktop installer move
out of `linux/` first -- they are not Flutter scaffolding and are still
needed; the entry now points at the packaged launcher and matches the
`--class=diet_guard_app` the wrapper passes, so the taskbar shows the app's
icon rather than a browser's.
install_arch.sh carries over the three traps each of which produced an
install that looked fine until launched: `dart build cli` rather than
`dart compile exe` (which refuses any package whose dependency graph has
native build hooks), `options=('!strip')` (makepkg would otherwise discard
the AOT snapshot, leaving a binary that runs as the bare Dart VM printing a
usage message), and no browser in `depends` (this machine's policy uninstalls
`chromium` seconds later, failing dependency resolution).
Also adds the frame-cadence instrument the performance claim is measured
with, armed by `--dart-define=DIET_GUARD_FRAME_STATS=1` and read with
`String.fromEnvironment` -- `bool.fromEnvironment` only accepts the literal
`true`, so `=1` would evaluate to false and a whole run would silently
produce no data. It reports frame-to-frame cadence rather than build/raster
durations, since work that fits the budget says nothing about the frame rate
actually achieved.

# Install the diet_guard_app launcher icon and .desktop entry for the Linux
|
|
# desktop.
|
|
#
|
|
# The desktop app is a Flutter *web* build shown in a Chrome app window (the
|
|
# Linux embedder manages only ~20fps at 4K), so the launcher starts the
|
|
# wrapper, which serves the build and opens the browser.
|
|
#
|
|
# Icon PNGs are pre-rendered and committed under desktop/icons/, so this script
|
|
# needs no image tooling at run time. Regenerate them with:
|
|
# PYTHONPATH=~/testsAndMisc python3 -m python_pkg.app_icons \
|
|
# generate --app diet_guard_app --linux-out desktop/icons
