CIAgent 6be95cf2f6 docs(P00): research findings — credential engine architecture + personas

ARCHITECTURE.md:
- D-024 sandbox isolation via unshare Linux user/mount/pid/net namespaces
  (probe-verified: in-ns uid=0, network isolated, no container runtime/sudo on box)
- D-025 sandbox scope = coding IDE only (design/sim deferred to v0.4)
- D-026 telemetry = WebSocket ingest + SQLite ordered event log (seq gap detection)
- D-027 first persistence = SQLite, protocol-wrapped stores (Trace/Grade/Variant/Defense)
- D-028 trace grading = deterministic digest features + LLM rubric (LLM never sees raw trace)
- D-029 variant generation = seeded template instantiation, seed persisted
- D-030 voice = provider-agnostic mock-first STT/TTS + browser fallback (D-014 mirror)
- D-031 extend ai-service (no new apps); D-032 single-box 1-5 concurrent sandboxes
- New engine component tables + v0.3 build order

PERSONAS.md (lead-developer assessment):
- new sandbox-engineer + voice-engineer custom personas (phase-specific)
- backend-engineer territory extended to engine persistence/APIs; ai-engineer re-scoped
  to model-facing grading/variant/voice logic; security-auditor stays inactive (KYC deferred)

A-101 corrected post-probe: bwrap absent -> unshare namespaces (verified)

.gitignore: ignore SQLite data + sandbox runtime dirs
