display-protocol -> library/protocol/display/, scanout-protocol ->
library/protocol/scanout/. Consumers import both directly, killing the cryptic
dp/sp aliases in virtio-gpu (now display_protocol / scanout_protocol) and the
runtime.display_protocol / runtime.scanout_protocol re-exports. runtime.display
(the client) still imports display-protocol by name; scanout has no runtime
client, so its runtime module import is dropped too.
zig build + test green; display-service, virtio-gpu, display-native,
display-reattach pass.
device-manager-protocol -> library/protocol/device-manager/. Its consumers
(pci-bus, usb-xhci-bus, the acpi discovery service, device-manager, device-list,
crash-test, and the not-yet-built intel-integrated display sub-driver) import the
module directly instead of through runtime.device_manager_protocol, which is
deleted. runtime.device_manager (the hello client) already imported the module
by name and is unchanged.
zig build + test green; device-manager, driver-restart, device-list, pci-scan pass.
input-protocol -> library/protocol/input/input-protocol.zig. Its five
consumers (usb-hid keyboard/mouse, ps2 keyboard/mouse, the input service) now
import the module directly and alias it input_protocol, replacing the
runtime.input_protocol re-export (deleted) and the inconsistent local `protocol`
aliases. runtime.input (the client) still imports the module by name.
zig build + test green; input, acpi-ps2, usb-hid pass.
vfs-protocol -> library/protocol/vfs/vfs-protocol.zig. fat, its only consumer,
now imports the module directly (const vfs_protocol = @import("vfs-protocol"))
instead of through runtime.vfs_protocol, and the runtime re-export is deleted.
The runtime's own client (runtime.fs) still imports the module by name.
zig build + test green; vfs, fat-mount pass.
Start the protocol tree: wire protocols move to library/protocol/<name>/,
entry file <name>-protocol.zig, module name unchanged. block and usb-transfer
are pure moves — every consumer already imports them by module name, so only
the b.addModule paths change and the empty system/services/block/ is removed.
block-protocol -> library/protocol/block/block-protocol.zig
usb-transfer-protocol -> library/protocol/usb-transfer/usb-transfer-protocol.zig
zig build + test green.
