Fix failing integration test after adding test HTML presets

comparison.json was stale (built from 2 test presets only) while
modlist_html/ now has 4 files. Regenerated comparison.json from all
presets to restore consistency.

Also added _SkipTest exception to the test harness so the
consistency check skips gracefully on a fresh clone (comparison.json
is gitignored) instead of raising AssertionError.

+### GUI package
+
+`gui/` is a CustomTkinter desktop application wrapping the CLI toolchain. Entry point is `gui.py` at the project root, which calls `gui.run_app()`.
+
+**Key files:**
+- `gui/__init__.py` — sets dark theme + blue color scheme; exports `run_app()`
+- `gui/app.py` — `ArmaModManagerApp` main window; manages view routing, config loading, thread-safe log queue, and background pipeline execution
+- `gui/wizard.py` — `SetupWizard` dialog shown on first launch when no `config.json` exists
+- `gui/_constants.py` — window dimensions, status color constants, file paths
+- `gui/_io.py` — `_QueueWriter` redirects stdout/stderr to a thread-safe queue so pipeline output streams into the Logs view
+
+**Views** (`gui/views/`): each inherits `BaseView`; `build()` runs once on creation, `refresh()` runs on each navigation:
+- `dashboard.py` — overview, status, quick stats
+- `mods.py` — browse and manage downloaded mods by group
+- `tools.py` — link/unlink, rename folders, sync missing mods, check server
+- `logs.py` — real-time log viewer fed from the stdout/stderr queue
+- `settings.py` — in-app editor for `config.json` (server URL, paths, credentials)
+
+**`selection.json`** — GUI selection state file, tracked in git. Persists which mods/groups are selected between GUI sessions. Written by the GUI; safe to delete (GUI recreates it on next save).
+
 ## Python Version Compatibility
 
 Minimum is Python **3.9**. All files that use `X | Y` union type annotations **must** have `from __future__ import annotations` as the first import. Without it, the `|` syntax raises `TypeError` at runtime on Python < 3.10. Every module in `arma_modlist_tools/` already has it; any new CLI script you add must include it too.
