sweep: pre-existing drift + matrix UDC entry + ignore 142MB EXE

Bundles drift left uncommitted from prior sessions and the UDC matrix
verify entry added today.

Drift items (all per session-progress.md, completed in earlier sessions
but never staged):

- playbook/check-bios.cmd (deleted, moved to BIOS/check-bios.cmd)
- playbook/migrate-to-wifi.ps1 (made no-op 2026-04-24 after the dnsmasq
  no-gateway fix removed the wired-NIC race that motivated it)
- playbook/preinstall/oracle/Install-Oracle11r2.cmd (post-OUI .ora copy
  added 2026-04-24)
- playbook/preinstall/oracle/tnsnames.ora (live tnsnames, 469 KB,
  deployed alongside the wrapper 2026-04-24)
- playbook/pxe_server_setup.yml (dnsmasq dhcp-option=3,6 commented,
  Oracle .ora deploy task added 2026-04-24)
- playbook/shopfloor-setup/BIOS/{check-bios.cmd, models.txt} (BIOS
  detection refinements)
- playbook/shopfloor-setup/Shopfloor/Force-Lockdown.bat
- playbook/shopfloor-setup/Shopfloor/Monitor-IntuneProgress.ps1
- playbook/shopfloor-setup/Shopfloor/SetShopfloorAutoLogon.bat (new)
- playbook/shopfloor-setup/Shopfloor/09-Install-PrinterInstallerMap.ps1
  (new, places PrinterInstallerMap.exe + Public Desktop shortcut at
  imaging time; manifest entry self-heals on tamper)
- playbook/shopfloor-setup/Shopfloor/lib/Show-IntuneDeviceQR.ps1 (new,
  standalone QR rendering for site that wanted just that piece)
- playbook/shopfloor-setup/gea-shopfloor-collections/{Install-eMxInfo.cmd.template,
  Restore-UDCData.ps1} (these were uncommitted in pre-rename Standard/;
  git mv didn't catch them because they were untracked at the time)
- docs/shopfloor-machine-imaging-guide.md (operator-facing how-to)

Matrix:
- common.test/matrix.json: add UDC verify entry to gea-shopfloor-collections
  row. Surfaces UDC silent-install issue (item H pending) instead of
  letting it pass silently.

.gitignore:
- PrinterInstallerMap.exe (142 MB) excluded. Track via LFS or stage on
  PXE server only - too big for regular git history. Untouched on disk
  so existing local copy still works.

playbook/migrate-to-wifi.ps1

-# migrate-to-wifi.ps1 - Invoked by FlatUnattendW10-shopfloor.xml as Order 5
-# during first logon, right after wait-for-internet.ps1 and right before
-# GCCH enrollment. Moves the machine off wired onto WiFi for the rest of
-# the imaging chain so the PXE ethernet cable can be safely disconnected.
+# migrate-to-wifi.ps1 - No-op as of 2026-04-24.
 #
-# Gated: if there is no physical Wi-Fi adapter on the machine (tower /
-# desktop case), the whole migration is a no-op. Previously this step
-# disabled all wired adapters unconditionally and then waited for WiFi
-# internet that could never arrive on towers, hanging first logon forever.
+# Previously this disabled all wired NICs at first logon to keep PPKG /
+# Intune enrollment routing internet traffic via WiFi. The wired NIC was
+# preferred by Windows because the PXE dnsmasq was handing out a default
+# gateway (dhcp-option=3,10.9.100.1) which Windows installed as a default
+# route, and the lower interface metric of wired beat WiFi. Internet-bound
+# traffic then black-holed at 10.9.100.1 (the PXE server, which doesn't
+# forward).
+#
+# That root cause was fixed by removing the dhcp-option=3 and =6 lines
+# from /etc/dnsmasq.conf on the PXE server. Without an advertised gateway
+# on the PXE side, Windows can't add a default route via wired, so all
+# internet traffic uses WiFi by default and the wired NIC stays harmless
+# for same-subnet PXE/SMB traffic to 10.9.100.1.
+#
+# Side effect of the original behavior was an eDNC race: eDNC autostart
+# would fire while the wired NIC was still disabled and hit WSAEINVAL
+# (Winsock 10022) trying to bind to a non-existent local IP, looping its
+# retry timer until a SYSTEM task re-enabled the NIC after SFLD creds
+# landed (often ~30+ min later). Keeping the NIC up the whole time
+# eliminates that race.
+#
+# Kept as a no-op file (instead of removed) so the unattend XML's Order 5
+# RunSynchronousCommand entry does not need to be re-numbered. If the
+# dhcp-option lines ever come back, this can be reverted to the disable
+# logic by restoring from git.
