# Wrap the timeglyph-lens macOS binary in a .app bundle (icon + Info.plist) so the
# GUI ships as a Homebrew Cask — a clickable app in /Applications (Launchpad /
# Spotlight / Dock), not a bare CLI on $PATH. A stable CFBundleIdentifier also
# gives the Accessibility-permission grant (the AX element picker) a stable
# identity across versions.
#
# Usage: bundle-lens-app.sh <lens-binary> <cli-binary> <version> [output-dir]
#   -> writes "<output-dir>/TimeGlyph Lens.app"  (default output-dir: cwd)
# The bundle uses the display-style name macOS GUI apps conventionally carry
# ("TimeGlyph Lens.app", like "Google Chrome.app"); the executable inside stays
# the hyphenated CLI name (timeglyph-lens).
#
# The `timeglyph` CLI is bundled ALONGSIDE the GUI in Contents/MacOS. That lets the
# cask expose both via `binary` stanzas and drop `depends_on formula:` — which is what
# makes `brew install --cask …` a genuine ONE-command install: Homebrew 6 refuses to
# load a formula the user did not name (an indirect `depends_on`) from an untrusted
# tap, aborting the whole install, whereas the explicitly-named cask is trusted. Cost:
# the CLI is duplicated (it also ships in the formula and the tarball).
