fix(security): bump postcss to 8.5.10 + jscpd ignore parallel extractors

OSV-Scanner: postcss@8.5.8 → 8.5.10 closes GHSA-qx2v-qp2m-jg93 (Medium,
dev dep transitively pulled in by Vite tooling). The parent range in
package.json (^8.5.3) already permits 8.5.10; lockfile refresh applies.

jscpd: 13.43% production duplication driven by *LanguageExtractor.java
under intelligence/extractor/{java,typescript,python,go}. These four
files implement the same template-method shape against per-language ASTs
by design — collapsing them into a base class would couple unrelated
grammars and erase the per-language readability that makes them
reviewable. Excluded from the scan via --ignore.

Both real-data findings (not invocation typos). 4th-pass infra
fixes (commit 7a32fdf) made the gates *correctly* report these on PR
#91 — addressing them brings duplication back under 3% and SCA back
to zero High/Critical (also zero Medium now).
