feat: Add assessment team guide for Brownhat Diagnostic execution

Browse Source 
New: assessment-templates/assessment-team-guide.md

Pre-engagement: access checklist (M365, AD, docs); tool preparation
with deployment times; what to do if access is not ready.

Day 1 discipline: deploy ASTRAL and PULSAR before workshops start.
Step-by-step ASTRAL and PULSAR deployment commands. Passive external
scan in background. Microsoft Secure Score baseline.

Workshop signals: table of client statements -> likely findings ->
what to check on Day 2. Feeds technical assessment planning.

Day 2-3 tool runs in sequence:
1. CAExporter (30 min) - CA policy reality check; report-only mode;
   exclusion groups defeating the purpose
2. BloodHound (1-2h) - 5 required queries; KRBTGT last set check;
   Domain Admins on workstations; service account attack paths
3. Elysium (2-4h) - privilege requirements noted; privacy model
   explanation; what to document
4. Purple Knight (30 min) - indicators to focus on; cross-reference
   with BloodHound
5. Entra ID manual checks (1h) - app registrations, guest accounts,
   MFA registration status, AD Connect sync account
6. Intune/endpoint check (30 min) - via ASTRAL output
7. External attack surface (30-60 min) - Nmap, Shodan, crt.sh
8. Firewall rule review (30-60 min) - what to look for
9. Backup spot check (30 min) - the 'green tick' test

Kill chain synthesis: explicit step-by-step method for tracing
from outside to organisational failure.

Finding triage: kill chain test table; common priority inflation
mistakes.

Quick wins: 8-item checklist; three tests a quick win must pass.

Report structure: 5 sections, target 15-25 pages, specific guidance
per section including what makes a weak vs strong finding.

ASERAL/PULSAR handover requirements before leaving site.

9 common assessment mistakes named explicitly.

Post-assessment checklist: 10 items before submitting the report.

index.md and assessment-templates/README.md updated.
