Signal Scout v0.1.1

Patch release for the Markdown evidence renderer.

• Replaces custom fenced-code backtick escaping with structurally safe
  indented Markdown code blocks.
• Preserves visible escaping for terminal, C1, and bidirectional controls.
• Keeps raw HTML encoded in prose fields and canonicalizes link destinations.
• Verified by 117 unit/integration tests, 14 desktop/mobile browser and WCAG
  gates, a full dependency audit, and a clean CodeQL run.

This is the recommended GitHub source release. It is not published to npm and
does not represent a hosted Signal Scout service.
