feat: backport Opus 4.7 + adaptive thinking, remove scan tools, add --help to scripts

Backport upstream Shannon PRs #325, #327, #328:

- Update large model default to claude-opus-4-7, add adaptive thinking
  configuration (auto-enabled on Opus 4.6/4.7, opt-out via
  CLAUDE_ADAPTIVE_THINKING=false), filter thinking blocks from message
  content, bump claude-agent-sdk to ^0.2.114
- Remove unused scan tools (nmap, subfinder, whatweb, schemathesis) from
  Dockerfile, prompts, and docs; remove dead 'tool' error type from
  PentestErrorType; redact URLs in preflight info logs
- Add --help flag to save-deliverable and generate-totp CLI scripts
