Adapts the SDLC example template to Privileged Escalation's actual agents,
branch strategy, and review pipeline. Adds SDLC.md reference to all 7 agent
AGENTS.md files so every agent reads it on heartbeat.
Security review is handled within the CTO review stage (no dedicated security
agent). The tri-branch dev/uat/main model from the example is replaced with our
actual single-branch (feature → main) workflow.
