refactor: Reorganize repository structure for better maintainability

Major structural improvements: - Created organized directory structure with logical separation - bin/ directory for legacy scripts (poc.sh, prod.sh) - config/ directory for configuration templates - tests/ directory for test framework - docs/ directory for documentation (ADRs) Enhanced build system: - Comprehensive Makefile with 20+ commands for development workflow - Full CI/CD pipeline support (test, lint, security-check) - Vendor integration testing for git vendor inclusion scenarios - Development environment setup and configuration management Updated test framework: - Smart path resolution for both organized and vendored structures - Improved vendor compatibility testing - Enhanced error handling and timeout protection Documentation updates: - Updated README with new directory structure - Comprehensive command reference and usage examples - Clear vendor integration guidelines - Architecture Decision Record for Node.js version management Files moved: - poc.sh, prod.sh → bin/ (legacy scripts) - bitwarden-config.conf.sample → config/ - test-secrets-manager.sh → tests/ - ADR-Node.md → docs/ All path references updated to maintain full functionality. This reorganization improves maintainability while preserving compatibility for git vendor inclusion scenarios. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+# ADR-001: Node.js Version Management Strategy
+
+## Status
+Proposed
+
+## Context
+
+The TSYS Secrets Manager project needs to make an architectural decision regarding Node.js version management across development, staging, and production environments. This decision impacts:
+
+- Development workflow and environment consistency
+- Production stability and security posture
+- Operational complexity and maintenance overhead
+- Compliance with enterprise security policies
+- Integration with existing shell scripting frameworks
+
+As this project will be git vendor included into shell scripting frameworks, the Node.js management approach must be portable and not introduce complex dependencies on the consuming systems.
+
+## Decision Drivers
+
+1. **Security and Compliance**: Enterprise security requirements mandate automated security updates and clear audit trails
+2. **Operational Simplicity**: Minimize operational overhead and complexity in production environments
+3. **Development Efficiency**: Enable developers to work with appropriate Node.js versions for different projects
+4. **Vendor Integration**: Support clean integration when vendored into other shell scripting frameworks
+5. **Stability**: Ensure production deployments are stable and predictable
+6. **Version Flexibility**: Ability to test and deploy with specific Node.js versions when needed
+
+## Options Considered
+
+### Option 1: MISE (Modern Infrastructure Software Engineering)
+**Description**: Use MISE for polyglot runtime version management across all environments.
+
+**Pros**:
+- Zero-overhead performance (no shims, direct binary execution)
+- Multi-version support with automatic project-based switching
+- Modern Rust-based implementation with enhanced security
+- Excellent developer experience with unified tooling
+- Support for `.nvmrc` and other standard version files
+- Task runner capabilities
+
+**Cons**:
+- Additional operational complexity in production
+- Custom security update processes required
+- Not managed by distribution security teams
+- Requires team training and adoption
+- May complicate vendor integration scenarios
+
+### Option 2: System Package Manager (Debian apt)
+**Description**: Use distribution-provided Node.js packages for all environments.
+
+**Pros**:
+- Managed by Debian security team with automatic updates
+- Battle-tested in enterprise environments
+- Integration with existing configuration management
+- Clear audit trails and compliance support
+- Minimal operational overhead
+- Standard enterprise security practices
+
+**Cons**:
+- Often outdated versions (significant lag behind releases)
+- Limited to single system-wide version
+- Cannot easily test multiple Node.js versions
+- May not support latest language features
+- Difficulty matching exact versions across environments
+
+### Option 3: Containerized Deployment with Official Images
+**Description**: Use official Node.js Docker images with pinned versions.
+
+**Pros**:
+- Reproducible deployments with exact version control
+- Security scanning and automated vulnerability management
+- Isolation from host system dependencies
+- Industry standard approach for modern deployments
+- Easy version management through Dockerfile
+
+**Cons**:
+- Requires container orchestration infrastructure
+- Additional complexity for simple script deployments
+- May be overkill for shell script frameworks
+- Learning curve for container-naive environments
+
+### Option 4: Hybrid Approach
+**Description**: Use different tools for different environments and use cases.
+
+**Pros**:
+- Optimized approach for each environment's specific needs
+- Flexibility to choose best tool for each scenario
+- Can evolve strategy as requirements change
+
+**Cons**:
+- Increased complexity managing multiple approaches
+- Potential for environment drift and inconsistencies
+- More documentation and training required
+
+## Decision
+
+**Selected: Option 4 - Hybrid Approach with System Packages as Primary**
+
+### Primary Strategy:
+- **Production Environments**: Use Debian system packages (apt) for Node.js installation
+- **Development Environments**: Use MISE for flexibility and multi-version testing
+- **Vendor Integration**: Document both approaches, default to system packages
+
+### Rationale:
+
+1. **Security-First Production**: System packages provide the security posture required for enterprise production environments with automated security updates and established audit trails.
+
+2. **Development Flexibility**: MISE enables developers to test across multiple Node.js versions and maintain development-production parity when needed.
+
+3. **Vendor-Friendly**: When this project is vendored into shell scripting frameworks, defaulting to system packages minimizes external dependencies and complexity for consuming systems.
+
+4. **Gradual Adoption**: Teams can start with system packages and adopt MISE for development as needed, without disrupting production systems.
+
+## Implementation Guidelines
+
+### For Production Deployments:
+```bash
+# Install Node.js via system package manager
+sudo apt update
+sudo apt install nodejs npm
+
+# Verify installation
+node --version
+npm --version
+```
+
+### For Development Environments:
+```bash
+# Install MISE
+curl https://mise.run | sh
+
+# Configure for project
+mise use node@18.17.0
+mise use node@20.9.0  # For testing newer versions
+
+# Project-specific configuration
+echo "node 18.17.0" > .tool-versions
+```
+
+### For Vendor Integration:
+- Default installation scripts should use system packages
+- Provide optional MISE support for advanced users
+- Document both approaches clearly
+- Include version compatibility matrix
+
+## Consequences
+
+### Positive:
+- Production systems maintain enterprise security standards
+- Development teams gain version management flexibility
+- Reduced vendor integration complexity
+- Clear separation of concerns between environments
+- Future migration paths remain open
+
+### Negative:
+- Increased documentation requirements
+- Potential for environment drift if not managed properly
+- Team training required for both approaches
+- Slightly more complex CI/CD pipelines
+
+### Neutral:
+- Need to maintain compatibility with both package management approaches
+- Version testing required across both installation methods
+
+## Compliance and Security Considerations
+
+### System Package Approach:
+- Automatic security updates via `unattended-upgrades`
+- Integration with enterprise vulnerability scanners
+- Standard audit procedures apply
+- Compliance with distribution security policies
+
+### MISE Approach (Development Only):
+- Manual security update processes
+- Custom vulnerability monitoring required
+- Developer responsibility for version management
+- Clear policies needed for version selection
+
+## Monitoring and Metrics
+
+### Track:
+- Node.js version distribution across environments
+- Security update lag time between environments
+- Developer adoption of MISE in development
+- Issues related to version mismatches
+
+### Success Criteria:
+- Zero production security incidents related to Node.js versions
+- <1 week lag time for critical security updates in production
+- >90% developer satisfaction with version management workflow
+- Successful vendor integrations with minimal friction
+
+## Review Schedule
+
+This ADR should be reviewed:
+- Quarterly for the first year
+- Annually thereafter
+- When major Node.js LTS versions are released
+- After significant security incidents
+- When vendor integration patterns change
