feat: Dell Command | Update step (step 11) + download link on landing page

scripts/11-dell-update.ps1:
- Detects Dell via Win32_ComputerSystem.Manufacturer (skips silently on non-Dell)
- Installs Dell.CommandUpdate.Universal via winget (silent)
- Runs dcu-cli.exe /applyUpdates -silent -reboot=disable (all categories)
- BIOS/firmware staged, completes on restart after deployment
- Exit codes 0/1/5 all treated as success

Deploy-Windows.ps1:
- Added Step 11 - Dell Command | Update (dellUpdate=true default)

internal/runner/runner.go, internal/config/config.go:
- dellUpdate step registered in AllSteps() and DefaultConfig

web/spec/index.html:
- Step 11 card with flag-done rows, sidebar link, comment-widget issue #16
- STEP_SCRIPT map updated for step-dell

web/index.html:
- Dynamic download strip: fetches latest Forgejo release via API,
  shows Download xetup.exe with version + file size
- Updated Go TUI card text (no longer "zatim ve vyvoji")

web/data/descriptions.json: regenerated (13 scripts, 80 items)

Forgejo: issue #16 created, release v0.1.0 published with xetup.exe (5.2 MB)

+.SYNOPSIS
+    Detects Dell hardware, installs Dell Command | Update, and applies all available updates.
+
+.DESCRIPTION
+    Checks Win32_ComputerSystem.Manufacturer - if not Dell, the step exits silently without
+    error so the same deployment script works on any hardware. On Dell machines, installs
+    Dell Command | Update (Universal) via winget and immediately runs /applyUpdates with
+    -reboot=disable. This covers drivers, firmware, and BIOS. BIOS and firmware updates are
+    staged at this point and finalize automatically during the restart that closes the
+    deployment. The operator does not need to run a separate update pass after setup.
+
+.ITEMS
+    detekce-dell-hw-win32-computersystem: Reads Win32_ComputerSystem.Manufacturer. If the string does not contain "Dell", the entire step is skipped without error. The deployment continues normally on HP, Lenovo, or any other brand.
+    instalace-dell-command-update-via-winget: Installs Dell.CommandUpdate.Universal silently via winget. This is the current DCU generation (v5+) that supports Latitude, OptiPlex, Precision, Vostro, and XPS on Win10 and Win11.
+    spusteni-vsech-aktualizaci-drivery-firmware-bios: Runs dcu-cli.exe /applyUpdates -silent -reboot=disable. Covers driver, firmware, and BIOS categories in a single pass. The -reboot=disable flag prevents DCU from rebooting mid-deployment.
+    bios-firmware-staging-reboot: BIOS and firmware updates are staged by DCU and finalize on the next system restart. The deployment already ends with a restart (step 09 - computer rename), so no extra reboot is needed.
