Paul BakausandClaude Opus 4.6 00d485659a Fix false positives: bg-black opacity modifiers and background-image contrast
Two detector bugs that produced false positives on sites like uselinkshot.com:

1. The bg-black regex matched Tailwind opacity modifiers (bg-black/3,
   hover:bg-black/5) because / is a word boundary. Added negative lookahead.

2. resolveBackground ignored url() background-images, walking past them to
   the body's white bg. White text on a dark hero image was flagged as
   1.0:1 white-on-white. Now bails on url() images like it does for gradients.

Also: extension build auto-generates dist/extension.zip, version bumps for
CLI (2.1.7) and extension (1.0.1).
