Mike Swanson 116778cad9 fix: Remove all non-DOS 6.22 commands from batch files ...

Critical compatibility fixes - DOS 6.22 does not support many Windows
batch file features. Removed all incompatible commands and replaced
with DOS 6.22 compatible alternatives.

Issues Fixed:

1. DEPLOY.BAT - Removed SET /P (interactive input)
   - Changed from: SET /P MACHINE=Machine name:
   - Changed to: SET MACHINE=%1 (command-line parameter)
   - Usage: DEPLOY.BAT TS-4R
   - DOS 6.22 does not support SET /P

2. CHECKUPD.BAT - Removed SET /A (arithmetic) and GOTO :EOF
   - Removed 6 instances of SET /A counter arithmetic
   - Replaced numeric counters with flag variables
   - Changed from: SET /A COMMON=COMMON+1
   - Changed to: SET COMMON=FOUND
   - Replaced GOTO :EOF with actual labels
   - Changed display from counts to status messages

3. STAGE.BAT - Removed FOR /F (file parsing)
   - Changed from: FOR /F "skip=1 delims=" %%L IN (...) DO
   - Changed to: TYPE C:\AUTOEXEC.BAT >> C:\AUTOEXEC.TMP
   - DOS 6.22 only supports simple FOR loops

Created check-dos-compatibility.ps1:
- Automated scanner for DOS 6.22 incompatible commands
- Checks for: SET /P, SET /A, IF /I, FOR /F, FOR /L, FOR /R,
  GOTO :EOF, %COMPUTERNAME%, &&, ||, START, invalid NUL usage
- Scans all BAT files and reports line numbers
- Essential for preventing future compatibility issues

Verification:
- All files maintain CRLF line terminators
- All commands tested for DOS 6.22 compatibility
- No SET /A, SET /P, FOR /F, GOTO :EOF remaining
- CHOICE commands retained (CHOICE.COM exists in DOS 6.22)

Impact:
- DEPLOY.BAT now requires parameter: DEPLOY.BAT TS-4R
- CHECKUPD.BAT shows "Updates available" vs exact counts
- STAGE.BAT copies all AUTOEXEC lines (duplicate @ECHO OFF harmless)
