[FEATURE] [0.0.4-alpha] Add JSON Output for Version Command

[codvy8282]

Project

cortex-cli

Description

The version command outputs plain text but doesn't support JSON output for programmatic version checking.

Use Case

$ cortex --version
cortex 0.0.4-alpha

$ cortex --version --json
error: unexpected argument '--json'

Proposed Solution

1. Support --version --json or cortex version --json
2. Output structured version info:

{
  "version": "0.0.4-alpha",
  "build": "...",
  "commit": "...",
  "platform": "windows"
}
