feat(audit): add color support to audit table output

Added colorized output to make audit, make outdated, and all audit
commands for improved visual distinction of tool statuses.

Changes:
1. Added CLI_AUDIT_COLOR environment variable (default: 1/enabled)
2. Added ANSI color codes to cli_audit/render.py:
   - GREEN: Up-to-date tools
   - YELLOW: Outdated installed versions
   - BOLD_GREEN: Newer available versions
   - BLUE: Not installed tools
3. Updated render_table() to apply colors based on status
4. Added colorize() helper function
5. Updated Makefile targets to enable colors:
   - audit, audit-offline, outdated
   - audit-%, audit-offline-%

Color scheme:
- UP-TO-DATE: green installed, green latest
- OUTDATED: yellow installed, bold green latest
- NOT INSTALLED: blue installed, blue latest
- CONFLICT: yellow installed, bold green latest

Disable with: CLI_AUDIT_COLOR=0 make audit
