`ocm describe types` Command

[jakobmoellerdev]

Description

Implement the primary CLI entry point for documentation. The command should guide the user from a list of subsystems down to specific type details.

Acceptance Criteria:

• ocm describe types (level 0): Lists subsystems in a table.
• ocm describe types <subsystem> (level 1): Shows guides and lists available types.
• ocm describe types <subsystem> <type> (level 2): Full schema documentation.
• TextRenderer providing a high-quality ANSI-styled terminal output.

Example for output of ocm describe types input-method file for inspiration:

================================================================================
TYPE:   file
ALIAS:  v1/file
SYSTEM: input-method (Resource/Source Input Methods)
SOURCE: Core OCM
================================================================================

DESCRIPTION:
  The 'file' input method ingests a single file from the local filesystem. 
  It is the most common way to add simple artifacts to an OCM component.

GUIDES & USAGE
--------------------------------------------------------------------------------

GUIDE: Basic Usage in component-constructor.yaml
  Summary: How to use the 'file' input method to add a text file resource.

  Section: Configuration Structure
    Content:
      Specify 'type: file' and provide the relative 'path' to the file.
    Example (ocm.yaml):
      resources:
        - name: readme
          type: plainText
          input:
            type: file
            path: ./README.md

  Section: Compression
    Content:
      Set 'compress: true' to automatically GZip the file during ingestion.
    Example (ocm.yaml):
      input:
        type: file
        path: ./large-data.bin
        compress: true
