PLAN.md §5.4. The status section still announced Phase 1 as built and
Phase 2 as next, four phases later -- it is the first thing a visitor to
this repo reads, and it has been wrong since Phase 2 merged.
- The phase table now shows 1-4 built on `edge` and 5 in progress, and
the opening says what the binary actually does.
- "What the cutover is waiting on" is stated, because "nothing is
released yet" invites the question: Phase 5, and the Windows SCM half
never having been executed anywhere.
- "Planned commands" is now "Commands". All four are implemented.
- RUNICGATEWAY_STATE_DIR was described as relocating install.json. Since
Phase 2 it relocates everything the installer writes, including the
sidecar binary, and suppresses service registration -- an out-of-date
description of where a tool writes is worse than none.
- A design-constraint bullet for the backup behaviour Phase 5 adds.
