dwm-titus v0.6.0

This release advances dwm-titus from a window-manager setup into a cohesive,
Fedora-first X11 desktop while preserving the existing-system installer for
Debian, Arch, and RHEL-family systems.

Highlights

• Adds the read-only Quickshell Settings foundation, capability discovery, and
  explicit available/unsupported states.
• Makes the checksum-verified Herdr workspace the default interactive terminal
  experience when installed, while keeping direct command launches predictable.
• Improves multi-monitor Quickshell panels, monitor-local workspaces and popups,
  fullscreen stacking, tray behavior, and screenshot handling.
• Adds reproducible release checks, nested-X11 coverage, QML linting, and
  Debian/Arch/Fedora container validation.
• Fixes Fedora 44 image package resolution by removing the unavailable
  nwg-look RPM; GTK Settings is now shown only when that optional tool exists.

See CHANGELOG.md
for the complete list of changes.

Assets

• dwm-titus-0.6.0.tar.gz: portable source archive.
• dwm-titus.iso: standard Fedora 44 x86_64 UEFI installer.
• dwm-titus-nvidia.iso: Fedora 44 x86_64 UEFI installer with the documented
  RPM Fusion NVIDIA driver policy.
• dwm-titus-0.6.0-SHA256SUMS: SHA-256 checksums for all three artifacts.

Validation

• Release source: 3d0ab667220bd89408292d7f236e3d7a8d3f7c7f.
• Full local make check and reproducible make release-check passed.
• Nested-X11 dwm, monitor-tag, Quickshell health/settings, and near-idle shell
  checks passed; QML lint completed with the repository's known type-map
  warnings only.
• Rootful Podman validation passed on Debian 13, Arch Linux latest, and Fedora
  44, including package resolution, clean builds, and staged installs.
• Exact-head GitHub CI and CodeQL passed.
• The Fedora 44 Server netinst source was verified against Fedora's signed
  x86_64 checksum before both installer variants were built.
• Both images were inspected to confirm the embedded release source, selected
  Kickstart, and standard-versus-NVIDIA boot arguments.
• The standard image completed an automated Fedora 44 UEFI Anaconda install in
  a clean KVM guest, rebooted from the installed disk, reached LightDM, and
  entered a working dwm session with the managed Quickshell panel rendered.

Known limitations

• The NVIDIA image received static, build, and payload validation but was not
  installed on physical NVIDIA hardware for this release.
• Secondary distribution coverage used clean containers and staged installs;
  no full graphical Debian, Arch, or non-Fedora RHEL session was exercised.
• The dedicated Fedora images disable SELinux by the project's documented image
  policy. Existing-system installs do not change the host SELinux state.
