enricobuehlerandClaude Opus 5 553676282a feat(windows): the brand reads Punktfunk on every device Windows shows
Device Manager, the firewall list and the monitor name all said "punktfunk". The brand
is Punktfunk.

Renamed: the [Strings] blocks of all four driver INFs (device descriptions, install
disks, provider, manufacturer), the `description` on every SwDeviceProfile the host
creates, pf-mouse's HID manufacturer + product strings, pf-vdisplay's IddCx endpoint
friendly + manufacturer names, the EDID 0xFC display-name descriptor — so Windows now
shows `Generic Monitor (Punktfunk)` — and the netsh firewall rule names.

The EDID edit is a single byte (0x70 -> 0x50) and needs no hand-patched checksum:
Edid::generate_with already recomputes both block checksums after patching the serial.

Deliberately left lowercase, because these are IDENTITIES rather than display names and
renaming them would orphan installed state:

  * the SwDeviceCreate enumerator `w!("punktfunk")` — it IS the SWD\PUNKTFUNK\... path
    every pad instance id is built from
  * pf-paths' `join("punktfunk")` — C:\ProgramData\punktfunk
  * the CN=punktfunk-driver cert subject, which purge_driver_certs and both driver build
    scripts match by string
  * install.rs' `lo.contains("punktfunk virtual display")` probes, whose haystack is
    to_ascii_lowercase()d, so they already match the capitalised name

Nothing is orphaned by the renames that DID happen either: netsh rule names,
Get-NetFirewallRule -DisplayName and PowerShell's -match are all case-insensitive, so
the firewall delete paths and reset-pf-vdisplay.ps1's -AdapterName / -GhostMatch
defaults still reap what every release up to 0.22.1 created.

Cosmetic, with two consequences worth knowing: it takes a driver rebuild + re-sign to
appear at all, and an existing devnode keeps its cached FriendlyName until it is
recreated.

;/*++
; punktfunk virtual Xbox 360 XUSB companion — a non-HID UMDF2 driver that registers the XUSB
; device-interface GUID {EC87F1E3-...} and answers the buffered XInput IOCTLs, so classic
; XInputGetState() reads the pad without a kernel bus driver (the HIDMaestro approach). System class,
; hosted by the in-box WUDFRd reflector. Created per-session by the host via SwDeviceCreate
; (hardware id `pf_xusb`); `root\pf_xusb` is the devgen/devcon test id.
