Chore: Organize poc-opencode-server into logical directory structure

[tbrandenburg]

Problem

The dev/poc-opencode-server/ directory contained 33+ files in a flat structure, making it difficult to navigate and understand the organization of planning documents, guides, demos, scripts, and results.

Solution

Reorganized all files into a logical 6-directory structure:

• 00-planning/ - Research and planning documents (POC_NOTES, FINDINGS, WORK-CLI-INTEGRATION)
• 01-guides/ - Step-by-step user guides (QUICKSTART, APPLICATION_GUIDE, SDK-EVALUATION, etc.)
• 02-reference/ - Technical reference documentation (INDEX, SUMMARY, AGENTS-MODELS-PERMISSIONS)
• 03-demos/ - Working code examples (11 demo files)
• 04-scripts/ - Automation scripts (explore.sh, VERIFY.sh)
• 05-results/ - Test results and logs

Changes

• Created 6 numbered directories for logical grouping
• Moved all 33 files into appropriate directories
• Added .gitignore to exclude node_modules/ from version control
• Updated README.md with new structure overview and navigation links
• Updated MANIFEST.md with complete file organization reference
• Enhanced package.json with npm scripts reflecting new paths:
  • npm run demo - Main ACP demo
  • npm run demo:sdk - SDK testing
  • npm run demo:resume - Session resumption
  • npm run verify - Environment verification

Testing

✅ All 303 unit tests passed
✅ Directory structure verified with tree command
✅ File organization confirmed via git status

Example Structure

dev/poc-opencode-server/
├── 00-planning/          # Research docs
├── 01-guides/            # User guides  
├── 02-reference/         # API reference
├── 03-demos/             # Working code (11 files)
├── 04-scripts/           # Automation
├── 05-results/           # Test results & logs
├── README.md             # Updated with navigation
├── MANIFEST.md           # Complete file index
└── package.json          # npm scripts

Notes

• Root .gitignore still excludes entire dev/ directory (as per project guidelines)
• This PR force-adds the organized PoC files for preservation
• PoC is frozen as of 2026-02-02 for historical reference
• All working demos and documentation preserved in organized structure
