base -> fb421083:
- fbcond: retry handoff while display driver is not ready (bounded
250x10ms; fixes the 2026-07-20 '-vga std' boot freeze at 'Performing
handoff' where a transient not-ready driver left the framebuffer VT
permanently blank)
- xhcid/virtio-netd: info-level IRQ/MSI-X delivery and reactor startup
milestones for runtime-proof observability
- usb: demote diagnostic ATTACH/HUBFLOW traces to debug!
- usbhubd: gate port-indicator SetPortFeature on hub capability
userutils -> 3b02e0b9:
- getty: harden the console<->PTY bridge against transient
read/write/event errors (log-and-continue instead of panic; a panic
here killed the live shell's I/O)
