[OC-760] Module directory version freeze & install

[cvaske]

Add oc module freeze and oc module install-freeze commands

Implements a pip-style freeze/restore workflow for OpenCRAVAT modules.

oc module freeze outputs all installed modules as a JSON array with
name, version, and type fields. Use -i/--include-hidden to include
hidden modules. Output goes to stdout and can be redirected to a file.

oc module install-freeze reads a freeze JSON file and installs the
pinned versions. Analogous to pip install -r requirements.txt.

Options for oc module freeze:

• -i, --include-hidden Include hidden modules in output
• --md MD Specify the root directory of OpenCRAVAT modules

Options for oc module install-freeze:

• freeze_file Path to freeze JSON file, or - to read from stdin
• -f, --force Reinstall even if the correct version is already installed
• -y, --yes Proceed without prompt
• --skip-dependencies Skip installing dependencies
• --md MD Specify the root directory of OpenCRAVAT modules

Example usage:

  # Save current module state
  oc module freeze > modules.json

  # Restore pinned modules on another system
  oc module install-freeze modules.json

  # Non-interactive restore
  oc module install-freeze -y modules.json

  # Pipe directly (no intermediate file)
  oc module freeze | oc module install-freeze -

  # Force reinstall of all pinned versions
  oc module install-freeze -f -y modules.json

Please change --skip-dependencies to --include-dependencies. Default to only installing the modules in the freeze file without handling module dependencies. Most likely if a freeze file is missing a dependency it's intentional from the user.

Remove --include-hidden and make it the default. Include all modules that are installed.
