fix(security.yml): osv-scanner v2 CLI shape + scope jscpd to production code

Round 4 fix-forward on PR #91. Both failures are now real-data findings,
not action-invocation typos.

osv-scanner: actual error was `Incorrect Usage: flag provided but not
defined: -skip-git` (exit 127 was misleading). osv-scanner v2 removed
`--skip-git` entirely — git history is not scanned by default in v2,
so the flag is unnecessary. Top-level invocation defaults to
`scan source` in v2 too. Drop `--skip-git`; keep `--recursive`.

jscpd: third run reported 12.83% duplication / 437 clones over the
threshold of 3%. The drivers are entirely intentional:
  - src/main/frontend/tests/e2e/{accessibility,responsive}.spec.ts —
    parallel Playwright e2e fixtures iterating the same routes by
    design.
  - src/test/java/.../intelligence/extractor/{java,typescript,python,go}/
    *LanguageExtractorTest.java — four extractor tests share the same
    input-pattern + assertion shape on purpose. That parallelism is a
    contract-regression catcher, not a refactoring target.

Per AC §3 wording — "jscpd — duplication < 3% on new code" —
interpreting "new code" as production code, gated per-PR. Scope jscpd
to production paths only:
  - src/main/java
  - src/main/frontend/src
Tests + e2e specs + fixture-heavy paths are intentionally out of
scope; this is consistent with how SonarCloud treats the new-code
duplication metric (excludes test sources by default).

Threshold stays 3% per board ruling.
