* feat(electron): sign and notarize mac release builds when Apple credentials are present
* fix(electron): work around codesign PID parsing for digit-leading app name in @electron/notarize
codesign interprets a bare '5chan.app' argument as process ID 5, so
@electron/notarize 2.5.0's pre-upload signature check fails with 'No such
process'. Backport the './' basename prefix from electron/notarize#245 as
a yarn patch until forge depends on notarize >= 3.x.
* docs(agent-playbooks): record codesign PID parsing surprise for digit-leading app name
* fix(ci): keep mac signing env consistent with certificate availability
Removes the direct `kubo` install-time dependency and switches Electron dev to the repo-managed Kubo downloader in `electron/start-ipfs.js`. This keeps the hooks upgrade in place while avoiding the `dist.ipfs.tech` timeout during `yarn install`.
Add public/icon.icns generated from icon.png. Update forge.config.js DMG maker and electron/main.js dev dock to use icon.icns. Fixes missing 5chan icon (default Electron icon shown).
Fix Android Capacitor compatibility by downgrading tar to 6.2.1. Add Windows-specific icon file for Squirrel installer. Update electron-forge to 7.8.0 and change DMG format to ULFO for macOS Sequoia compatibility. Add retry logic for transient SSL errors on Mac Intel runners.
