Add new license segv-1.1 for the SEGV License 1.1

[MGpromax]

Fixes #5247

Adds segv-1.1 for the SEGV License Version 1.1 (July 2026), text from the cloudcash LICENSE file referenced in the issue, homepage set to https://xn--gckvb8fzb.com/segv/.

As the issue notes, its Appendix B states it is adapted from the Hippocratic License 3.0 with modified and additional terms; this is recorded in the notes field, and category: Free Restricted mirrors the existing hippocratic-3.0 entry. owner: Unspecified since the license text itself names no steward -- happy to change if you prefer attributing it to its author.

Detection before this change: the text partially matched hippocratic-1.2 plus unknown license references. It now detects as segv-1.1 with score 100.

Validation (same for all six license additions from this batch):

• scancode-reindex-licenses runs clean
• self-detection and ignorables validation tests pass (--test-suite=validate tests/licensedcode/test_detection_validate.py), with ignorables generated by the test regen tooling rather than by hand
• pytest tests/licensedcode/test_license_models.py passes locally
