fix(sign): gon is gone, and the macOS bundle steps no longer run for every stack

Two things, and the second is why macOS was red across four unrelated stacks.

gon has been unmaintained since 2022. It did two jobs here: drive codesign
from a JSON file, and notarise. codesign is the thing it wrapped, so calling
it directly loses nothing and removes a dependency and two config files.
notarytool is Apple's supported replacement and staples the ticket, so an app
validates on first launch without a network round trip. Notarisation stays
opt-in because it needs an Apple ID and team ID that a build otherwise does
not; signing itself does not change shape.

--deep is deliberately absent from the codesign call: Apple deprecated it, and
nested code — Sparkle being the example already in this repository — wants
signing individually anyway.

The `Build .app zip file` step was gated on `runner.os == 'macOS'` and nothing
else. Harmless while every stack was Wails and every macOS build produced a
bundle. The go, cpp and deno stacks produce a binary and no bundle, so on
macOS the step asked ditto for a .app that never existed and took the job with
it — one ungated step showing up as four different stacks failing. It and the
two productbuild steps now skip with a notice when there is no bundle, which is
a fact about the stack rather than an error.

Also: the options matrix assertion read BUILD_OPTIONS by interpolation, and
-upxflags='--best --lzma' contains quotes that a shell assignment mangles. It
reads from env now, which is the same lesson as everywhere else.
