feat: Complete DOS update system with test data routing fix

Implemented comprehensive DOS 6.22 update system for ~30 test stations with
critical fix for test data database import routing.

## Major Changes

### DOS Batch Files (7 files)
- NWTOC.BAT: Download updates from network to DOS machines
- CTONW.BAT v1.2: Upload with separate ProdSW/LOGS routing (CRITICAL FIX)
- UPDATE.BAT: Full system backup to network
- STAGE.BAT: System file staging for safe updates
- REBOOT.BAT: Apply staged updates on reboot
- CHECKUPD.BAT: Check for available updates
- DEPLOY.BAT: One-time deployment installer for DOS machines

### CTONW v1.2 Critical Fix
Fixed test data routing to match AD2 sync script expectations:
- Software distribution: C:\ATE\*.EXE -> T:\TS-4R\ProdSW\ (bidirectional)
- Test data logging: C:\ATE\8BDATA\*.DAT -> T:\TS-4R\LOGS\8BLOG\ (upload only)
- Subdirectory mapping: 8BDATA->8BLOG, DSCDATA->DSCLOG, HVDATA->HVLOG, etc.
- Test data now correctly imported to AD2 database via Sync-FromNAS.ps1

### Deployment Infrastructure
- copy-to-ad2.ps1: Automated deployment to AD2 server
- DOS_DEPLOYMENT_GUIDE.md: Complete deployment documentation
- DEPLOYMENT_GUIDE.md: Technical workflow documentation
- credentials.md: Centralized credentials (AD2, NAS, Gitea)

### Analysis & Documentation (15 files)
- CTONW_ANALYSIS.md: Comprehensive compliance analysis
- CTONW_V1.2_CHANGELOG.md: Detailed v1.2 changes
- NWTOC_ANALYSIS.md: Download workflow analysis
- DOS_BATCH_ANALYSIS.md: DOS 6.22 compatibility guide
- UPDATE_WORKFLOW.md: Backup system workflow
- BEHAVIORAL_RULES_INTEGRATION_SUMMARY.md: C: drive integration

### Session Logs
- session-logs/2026-01-19-session.md: Complete session documentation

### Conversation Reorganization
- Cleaned up 156 imported conversation files
- Organized into sessions-by-date structure
- Created metadata index and large files guide

## Technical Details

### AD2 → NAS → DOS Sync Flow
1. Admin copies files to AD2: \192.168.0.6\C$\Shares\test\
2. Sync-FromNAS.ps1 runs every 15 minutes (AD2 → NAS)
3. DOS machines access via T: drive (\D2TESTNAS\test)
4. NWTOC downloads updates, CTONW uploads test data
5. Sync imports test data to AD2 database

### DOS 6.22 Compatibility
- No %COMPUTERNAME%, uses %MACHINE% variable
- No IF /I, uses multiple case-specific checks
- Proper ERRORLEVEL checking (highest values first)
- XCOPY /S for subdirectory support
- ASCII markers ([OK], [ERROR], [WARNING]) instead of emojis

### File Locations
- AD2: C:\Shares\test\COMMON\ProdSW\ (deployed)
- NAS: T:\COMMON\ProdSW\ (synced)
- DOS: C:\BAT\ (installed)
- Logs: T:\TS-4R\LOGS\8BLOG\ (test data for database import)

## Deployment Status

✅ All 7 batch files deployed to AD2 (both COMMON and _COMMON)
⏳ Pending sync to NAS (within 15 minutes)
⏳ Pending pilot deployment on TS-4R
📋 Ready for rollout to ~30 DOS machines

## Breaking Changes

CTONW v1.1 → v1.2: Test data now uploads to LOGS folder instead of ProdSW.
Existing machines must download v1.2 via NWTOC for proper database import.
