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.
