Fix: Use short git commit ID (7 chars) instead of full hash

Browse Source 
Research findings:
- Industry standard uses 'git rev-parse --short HEAD' (7 characters)
- Short hashes are more readable for logs and health endpoints
- Git automatically extends hash if 7 chars aren't unique
- Better for production deployment tracking and version verification

Changes:
- Dockerfile: Use --short flag to get 7-character commit ID
- README: Update examples to show short commit format (0e993d9)
- README: Add explanation of why short commits are used

Example health response:
{
  "git_commit": "0e993d9",  // 7 chars, not full 40-char SHA
  "version": "1.0.0"
}

**Version Tracking:** **Version Tracking:**
- `git_commit`: The Git commit SHA of the deployed code (auto-detected during build) - `git_commit`: Short Git commit SHA (7 characters) of the deployed code, auto-detected during build using `git rev-parse --short HEAD`
- `version`: Application version (defaults to 1.0.0, can be set via APP_VERSION env var) - `version`: Application version (defaults to 1.0.0, can be set via APP_VERSION env var)
This allows AI agents and monitoring tools to verify which version is currently running. This allows AI agents and monitoring tools to verify which version is currently running. The short commit ID is industry standard for deployment tracking, providing a balance between uniqueness and readability.
