The decide job already skips when main HEAD matches the nightly tag,
so this only builds when there are actual changes. Hourly means users
get nightly updates within an hour of merging to main.
Follows the same pattern as AppIcon-Debug (orange DEV banner) but with
a purple banner and "NIGHTLY" text. The nightly CI workflow now passes
ASSETCATALOG_COMPILER_APPICON_NAME=AppIcon-Nightly to xcodebuild so
the nightly app gets its own distinct icon.
Includes scripts/generate_nightly_icon.py for regenerating the icons
from the production AppIcon source files.
The nightly build is now a distinct app called "cmux NIGHTLY" with
bundle ID com.cmuxterm.app.nightly, allowing side-by-side installation
with the stable release. The nightly appcast URL is baked into the
app's Info.plist by CI, so no in-app channel switching is needed.
- Nightly workflow: rename app to "cmux NIGHTLY", set bundle ID to
com.cmuxterm.app.nightly, hardcode nightly Sparkle feed URL, publish
DMG as cmux-nightly-macos.dmg
- Remove "Receive Nightly Builds" toggle from settings
- Remove UpdateChannelSettings enum and simplify feed URL resolution
to just use SUFeedURL from Info.plist
- Remove UpdateChannelSettingsTests (no longer applicable)
Hardened runtime's library validation was verifying every dylib on load,
causing noticeable UI lag. Add entitlements file with
disable-library-validation to fix while keeping notarization support.
