feat: vendorizar as 10 skills do pilar de seguranca em skills/

Copia local (nao fork, nao submodule) de safedeps, sca-audit,
secrets-scan, code-review-security, api-security-review,
web-security-review, cve-triage, patch-prioritization,
dependency-scanning e hermaguard -- commit exato de origem e licenca
de cada uma em skills/NOTICE.md. Elimina o passo de clone externo
pro pilar de seguranca do wf-security-review: git clone deste repo
ja traz tudo funcional.

Corrige tambem o comando de instalacao pro Claude Code nos dois
READMEs e no docs/SKILLS.md: Claude Code exige um diretorio por
skill (skills/<nome>/SKILL.md), nao aceita os .md soltos que o
comando antigo copiava -- confirmado testando a instalacao real.

+Hermaguard Research Upgrades — Test Suite
+
+Tests the three research-backed tools against real files and real
+payloads. No mocks of the detection logic:
+
+  1. hermaguard-locate       — SHERLOC-style fault localization pre-pass
+  2. hermaguard-role-patterns — CLAWAUDIT-style agent-specific SAST rules
+  3. hermaguard-sanitize     — CodeSentinel-style injection-hardened context
