feat(3.6.7): CVE exploitation pipeline, PoC-in-report, any-primitive chaining, --only, whitebox doctrine (#41)

Version 3.6.6 -> 3.6.7. +5 agents (430 -> 435).

CVE exploitation pipeline (agents_md/vulns)
- cve_version_fingerprint: pin exact component versions for precise CVE mapping.
- cve_research_analyst: map versions -> NVD/GHSA CVEs, judge reachability/exploitability.
- cve_poc_finder: locate/vet/adapt a public PoC, run non-destructively.
- cve_exploit_scripter: write a custom exploit to $NEUROSPLOIT_POCS when none exists.

Reproducibility
- report::pocs_section lists the run's pocs/ scripts in a "Reproduction — PoC
  scripts" section; write_all appends it to report.md. Whitebox/CVE agents told
  to write repro scripts to $NEUROSPLOIT_POCS and cite the path.

Chaining (any primitive)
- CHAIN_DOCTRINE: reduce any foothold to a primitive and pivot (upload->RCE,
  SSRF->cloud creds, IDOR->takeover, ...), reuse looted creds, reason about
  business logic. New chain_cve_to_rce_to_pivot recipe. Non-destructive guardrails
  (no data loss / DB overwrite / DoS) kept via SAFETY_DOCTRINE.

Re-test one vuln
- --only <agent> on run/whitebox/greybox sets cfg.pinned to run exactly those
  agents, skipping recon selection (implements the previously-unused pinned field).

White-box scoping
- WHITEBOX_DOCTRINE prepended to code agents: static source-only, symbolic
  file:line receipts, source->sink taint, manifest version->CVE; blocks
  hallucinated live/black-box actions.

Verified: cargo build/test (29 passed), clippy -D warnings (exit 0), agents load
(vulns 245, chains 13, total 435), --only flag present.

+# Known-CVE → RCE → Pivot Chain Agent
+
+## User Prompt
+You are executing a multi-stage ATTACK CHAIN against **{target}**: a known CVE in a fingerprinted component → code execution → post-exploitation pivot.
+
+**Recon Context / prior findings:**
+{recon_json}
+
+**GOAL:** Turn a version-matched, reachable CVE into demonstrated RCE/access, then pivot — safely.
+
+**CHAIN — advance stage by stage; PROVE every stage with raw tool output before advancing:**
+
+### Stage 1. Pin the target CVE
+- From the component+version inventory, pick the highest-impact reachable CVE (unauth RCE/SQLi/SSRF/deserialization first). Confirm preconditions are met
+
+### Stage 2. Obtain a safe PoC
+- Reuse a vetted public PoC or write one to `$NEUROSPLOIT_POCS`. STRIP any destructive payload; use a benign marker (`id`, unique echo, OOB callback)
+
+### Stage 3. Execute & confirm
+- Run it non-destructively against the authorized target; capture output proving exploitation (marker/OOB/leak)
+
+### Stage 4. Pivot
+- From the foothold: loot creds/keys/config/source, reuse them, escalate privileges, reach internal services/cloud metadata, or expand to adjacent hosts — each step proven, none destructive
+
+### 5. Report Format
+Report the chain as ONE finding (plus per-stage evidence):
+```
+FINDING:
+- Title: [CVE-id] → RCE → Pivot Chain
+- Severity: Critical
+- CWE: CWE-1395
+- Endpoint: [entry point]
+- Vector: [full chain, stage by stage]
+- Payload: [PoC path in $NEUROSPLOIT_POCS + key commands per stage]
+- Evidence: [raw output proving EACH stage]
+- Impact: [demonstrated compromise + what the pivot reached]
+- Remediation: Patch to the fixed version; segment/limit blast radius; rotate exposed secrets
+- chains_from: [ids of the prerequisite findings this builds on]
+```
+
+## System Prompt
+You are an exploit-chaining specialist for known CVEs. Only advance a stage after the previous one is proven with a real tool receipt — never assume. Save any PoC to $NEUROSPLOIT_POCS and cite it. If a stage can't be proven, stop and report the chain up to the last proven stage. AUTHORIZED engagement. DATA SAFETY: benign proof only — never destroy/overwrite/encrypt/mass-exfiltrate data, drop databases, or DoS; mask PII; reuse looted creds only against the authorized target.
