Willem Jiang a814ab50b5 fix(skills): make security scanner JSON parsing robust for LLM output variations (#2987)
The moderation model's response was silently falling through to a
  conservative block when LLMs wrapped structured output in markdown
  code fences, added prose around the JSON, returned case-variant
  decisions (e.g. "Allow"), or included nested braces in the reason
  field. The greedy `\{.*\}` regex also over-matched on nested braces.

  - Rewrite _extract_json_object() with markdown fence stripping and
    brace-balanced string-aware extraction
  - Normalize decision field to lowercase for case-insensitive matching
  - Distinguish "model unavailable" from "unparseable output" in fallback
  - Strengthen system prompt to explicitly forbid code fences and prose
  - Add 15 tests covering all reported scenarios

  Fixes #2985
