refactor(repo): reorganize repository structure for improved navigation and maintainability

Implement comprehensive directory reorganization to improve discoverability,
logical grouping, and separation of concerns across documentation, scripts,
and infrastructure snapshots.

Major Changes:

1. Documentation Reorganization:
   - Created start-here-docs/ for onboarding documentation
     * Moved QUICK-START.md, START-HERE.md, GIT-SETUP-GUIDE.md
     * Moved GIT-QUICK-REFERENCE.md, SCRIPT-USAGE.md, SETUP-COMPLETE.md
   - Created troubleshooting/ directory
     * Moved BUGFIX-SUMMARY.md for centralized issue resolution
   - Created mcp/ directory for Model Context Protocol configurations
     * Moved OBSIDIAN-MCP-SETUP.md to mcp/obsidian/

2. Scripts Reorganization:
   - Created scripts/crawlers-exporters/ for infrastructure collection
     * Moved collect*.sh scripts and collection documentation
     * Consolidates Proxmox homelab export tooling
   - Created scripts/fixers/ for operational repair scripts
     * Moved fix_n8n_db_*.sh scripts
     * Isolated scripts with embedded credentials (templates tracked)
   - Created scripts/qol/ for quality-of-life utilities
     * Moved git-aliases.sh and git-first-commit.sh

3. Infrastructure Snapshots:
   - Created disaster-recovery/ for active infrastructure state
     * Moved latest homelab-export-20251202-204939/ snapshot
     * Contains current VM/CT configurations and system state
   - Created archive-homelab/ for historical snapshots
     * Moved homelab-export-*.tar.gz archives
     * Preserves point-in-time backups for reference

4. Agent Definitions:
   - Created sub-agents/ directory
     * Added backend-builder.md (development agent)
     * Added lab-operator.md (infrastructure operations agent)
     * Added librarian.md (git/version control agent)
     * Added scribe.md (documentation agent)

5. Updated INDEX.md:
   - Reflects new directory structure throughout
   - Updated all file path references
   - Enhanced navigation with new sections
   - Added agent roles documentation
   - Updated quick reference commands

6. Security Improvements:
   - Updated .gitignore to match reorganized file locations
   - Corrected path for scripts/fixers/fix_n8n_db_c_locale.sh exclusion
   - Maintained template-based credential management pattern

Infrastructure State Update:
   - Latest snapshot: 2025-12-02 20:49:54
   - Removed: VM 101 (gitlab), CT 112 (Anytype)
   - Added: CT 113 (n8n)
   - Total: 9 VMs, 3 Containers

Impact:
   - Improved repository navigation and discoverability
   - Logical separation of documentation, scripts, and snapshots
   - Clearer onboarding path for new users
   - Enhanced maintainability through organized structure
   - Foundation for multi-agent workflow support

Files changed: 90 files (+935/-349)
   - 3 modified, 14 new files, 73 renames/moves
