feat: restructure ht-docker-tools repository with enhanced Deno support and NVM integration

- Removed Dockerfile and added multiple Dockerfiles for various tools (ClickHouse, MongoDB, MinIO, Caddy, Redis) with Deno runtime.
- Updated package.json to reflect new repository structure and versioning.
- Added comprehensive README and technical notes for architecture overview and usage.
- Implemented build and test scripts for streamlined image creation and validation.
- Introduced bash scripts for NVM functionality in Docker images.

+# Image Support Files
+
+This directory contains helper scripts that enable NVM (Node Version Manager) functionality in Docker images.
+
+## Files
+
+### bash-with-nvm
+
+A wrapper script used as the SHELL directive in Dockerfiles. It loads NVM before executing any RUN command, enabling commands like:
+
+```dockerfile
+SHELL ["/usr/local/bin/bash-with-nvm"]
+RUN nvm install 18
+RUN node --version
+```
+
+### docker-entrypoint.sh
+
+An entrypoint script that ensures NVM is available at runtime. It handles:
+
+1. Loading NVM environment on container start
+2. Special handling for `bash -c` commands (common in CI/CD) to inject bashrc sourcing
+
+## Usage
+
+These files are copied into Alpine-based Docker images:
+
+```dockerfile
+COPY image_support_files/bash-with-nvm /usr/local/bin/bash-with-nvm
+COPY image_support_files/docker-entrypoint.sh /usr/local/bin/docker-entrypoint.sh
+RUN chmod +x /usr/local/bin/bash-with-nvm /usr/local/bin/docker-entrypoint.sh
+
+SHELL ["/usr/local/bin/bash-with-nvm"]
+ENTRYPOINT ["/usr/local/bin/docker-entrypoint.sh"]
+```
+
+## Why These Scripts Are Needed
+
+NVM is a bash function, not a binary. This creates challenges in Docker:
+
+1. **Build time**: Each RUN command starts a fresh shell without NVM loaded
+2. **Runtime**: Container commands don't automatically have NVM available
+3. **CI/CD**: Non-interactive shells (bash -c) need special handling
+
+These scripts solve all three contexts.
+
+## Maintenance
+
+When updating NVM version, ensure compatibility with both scripts. The NVM_DIR path (`/usr/local/nvm`) must match across:
+- These scripts
+- Dockerfile ENV declarations
+- /etc/bash.bashrc configuration
