docs: design status notes reflect what is merged

range-reads.md opens with a table of milestones M0-M5 and the PRs that
merged them (#17-#21), replacing a header left garbled by earlier
merges, and each milestone's status names its PR. swmr.md says the
reader is merged (PR #19) and the writer does not exist. openclaw.md
links the Node package's known-issues entry.
