Adds Pipeline stages, Hierarchy Rules, Agent Roster, Status Transition
Rules, Security Review, and Work Distribution sections. Expands Branch
Strategy, Pull Requests, PR Review Policy, Handoff Protocol, Status
Semantics, and CI/CD with detail previously only in per-agent SDLC.md
files. Hierarchy Rules updated: UAT/QA failures now route directly to
engineer rather than through CTO.
