claude-desktop-bin: bridge OVMF paths for Cowork

Cowork launches a QEMU VM and probes for OVMF UEFI firmware at the
Debian paths /usr/share/OVMF/OVMF_CODE{,_4M}.fd, which do not exist on
Slackware. Ship compatibility symlinks pointing at edk2-ovmf-x64, add
edk2-ovmf to REQUIRES, and document the Cowork deps and kvm group in
the README. Bump BUILD to 2.

+COWORK
+------
+Cowork runs the coding agent inside an isolated QEMU virtual machine.
+It requires:
+
+  - qemu (shipped with Slackware)
+  - edk2-ovmf (OVMF UEFI firmware; the REQUIRES of this package)
+  - virtiofsd (bundled inside this package)
+
+Cowork probes for the OVMF firmware at the Debian paths
+/usr/share/OVMF/OVMF_CODE{,_4M}.fd. This package installs compatibility
+symlinks there pointing at edk2-ovmf's /usr/share/edk2-ovmf-x64/ files,
+so Cowork finds them with no manual setup.
+
+For hardware acceleration the VM needs /dev/kvm, which is root:kvm 0660.
+Add your user to the kvm group so the VM does not fall back to slow
+software emulation:
+
+  # usermod -aG kvm <user>
