aivis 1.5.0 — search-safe training opt-out

The ecosystem's most-used AI blocklist (~4k stars) disallows all 166 known AI user-agents — including all seven search crawlers. If you wanted "don't train on me", you also got "don't recommend me, and drop me from Siri, Spotlight and Alexa".

python3 aivis.py --training-optout >> robots.txt

Blocks all 8 training crawlers, leaves all 7 search crawlers allowed. Every token sourced to vendor documentation. CI audits the generated output and fails if it ever blocks a search crawler.
