feat(dataforth-dos): Add DOS 6.22 Coding Agent and fix all batch files

DOS 6.22 Coding Agent (.claude/agents/dos-coding.md):
- 18 documented compatibility rules
- Validation checklist for all DOS batch files
- Known working constructs reference
- Error message troubleshooting guide

Batch file fixes for DOS 6.22 compatibility:
- CTONW.BAT v3.2: Removed %DATE%/%TIME%, square brackets
- ATESYNC.BAT v1.1: Removed square brackets, ERRORLEVEL checks
- CHECKUPD.BAT v1.4: Removed CALL :label subroutines, square brackets
- UPDATE.BAT v2.4: Removed square brackets, fixed NUL directory checks
- DOSTEST.BAT v1.2: Removed 2>NUL, square brackets, NUL checks

Key DOS 6.22 incompatibilities fixed:
- CALL :label (Windows NT+ only)
- %DATE% and %TIME% variables (don't exist)
- Square brackets in ECHO (cause errors)
- 2>NUL stderr redirect (not supported)
- IF NOT EXIST path\NUL (unreliable)
