fix: narrow moderation external override

Problem:
Skills using legitimate API integrations (process.env + fetch) were
permanently flagged as malicious due to CREDENTIAL_HARVEST being
classified as a malicious-level reason code. Once flagged, skills could
not recover to normal status even after clean VT and OpenClaw scans,
because:
1. syncModerationReasons used a partial-update path that only patched
   moderationReason without reconciling moderationFlags, moderationStatus,
   or moderationVerdict.
2. Static scan "you are now a/an" regex over-matched common skill
   preambles, adding spurious INJECTION_INSTRUCTIONS flags.
3. No mechanism existed for external scanner results (VT/LLM) to
   override static suspicious findings when both independently
   confirmed the skill as safe.

Solution:
- Downgrade CREDENTIAL_HARVEST from malicious.env_harvesting to
  suspicious.env_credential_access — env+network is suspicious, not
  malicious, for API integration skills (moderationReasonCodes.ts).
- Remove "you are now a/an" regex from markdown scanning to stop
  false INJECTION_INSTRUCTIONS flags (moderationEngine.ts).
- Add external scanner override in buildModerationSnapshot: when both
  VT and LLM report clean/benign, demote suspicious.* static codes
  from verdict calculation while preserving malicious.* codes and
  keeping all findings in evidence for transparency (moderationEngine.ts).
- Route syncModerationReasons through approveSkillByHashInternal for
  rows with sha256hash, ensuring full moderation state reconciliation.
  For legacy no-hash rows: malicious → escalateSkillByIdInternal
  (immediate hide); clean/suspicious → updateSkillModerationReasonInternal
  (partial fix, matches pre-existing behavior) (vt.ts, skills.ts).
- Add escalateSkillByIdInternal mutation for atomic emergency
  escalation by skillId (sets moderationReason, moderationFlags,
  moderationStatus, hiddenAt, isSuspicious) (skills.ts).
- Ensure approveSkillByHashInternal explicitly hides malicious skills
  by setting moderationStatus to 'hidden' (skills.ts).
- Bump MODERATION_ENGINE_VERSION to v2.1.0.

Frontend:
- Add StaticAnalysisDetail component to display static scan findings
  with severity-aware styling (SkillSecurityScanResults.tsx).
- getStaticGuidance now accepts vtStatus/llmStatus and shows "Confirmed
  safe by external scanners" (benign/green) when both are clean, instead
  of always showing yellow "Patterns worth reviewing" for critical
  severity findings.
- Render SecurityScanResults and disclaimer when only static findings
  are present (SkillHeader.tsx).

Testing:
- 7 new unit tests in moderationEngine.test.ts covering:
  - CREDENTIAL_HARVEST downgrade (suspicious, not malicious)
  - "you are now" no longer flagged in markdown
  - "ignore previous instructions" still flagged
  - buildModerationSnapshot: VT+LLM clean demotes suspicious codes
  - buildModerationSnapshot: malicious codes preserved despite clean VT+LLM
  - Single-scanner-clean does not demote suspicious codes
  - VT suspicious + LLM clean does not demote suspicious codes
- All existing tests pass with engine version bump to v2.1.0.

Follow-up needed (not in this commit):
- One-time backfill for already-misflagged skills (cursor-based,
  re-run approveSkillByHashInternal on isSuspicious=true + clean VT).
