PS/2 controller resilience:
- DisableFirst/DisableSecond commands now use retry (3 attempts)
instead of failing on first timeout
- Added 50ms settling delay before first command after firmware handoff
- Disable command failures are non-fatal (warn + continue) — a truly
absent controller fails later at self-test
- ps2d no longer panics on init failure — logs error and continues
so the system can still boot to login prompt without PS/2 input
Branding overrides:
- Added /etc/issue override with Red Bear OS pre-login banner
- Added /etc/motd override with Red Bear OS post-login message
- Fixes transaction conflict where userutils overwrites redbear-release
branding with upstream 'Redox OS' content
QEMU verified: boots to login prompt, no service errors
