Reformat the existing Markdown with prettier (closes #7)

The output of make fmt after the previous commit: README.md and TODO.md
are rewrapped at 80 columns, and the TODO.md Workflow list uses -
markers. No wording changes. REPO_POLICIES.md was already formatted.

Model: opus-5-5

 # Completed Steps
 
 - 2026-10-06: Formatted Markdown with prettier: `script/fmt` writes and
   `script/fmt-check` checks every Markdown file; prettier pinned in
-  `package.json` and `yarn.lock`, installed by `script/bootstrap` with a
-  pinned node and yarn; existing Markdown reformatted.

 - 2026-10-05: Brought the repo up to the standard layout: canonical
-  `.gitignore`, `.dockerignore` and `.editorconfig`; `lint` and `test`
-  phases in the `Dockerfile`, built by `script/lint` and `script/test`;
-  canonical `script/cibuild`, `script/docker` and CI workflow; no linter
-  installed on the host; re-vendored `REPO_POLICIES.md`.
-- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
-  Makefile shims, README Entrypoints section
-- 2026-06-28: Fixed errcheck lint failures; added compilation smoke test;
-  tidied go.mod.
-- 2026-06-28: Added repo scaffolding: README, LICENSE, Makefile,
-  Dockerfile, REPO_POLICIES.md, and Gitea CI.
-- 2026-02-12: Fixed SQLite database locking by removing parallel
-  processing; fixed Linux build via golang.org/x/sys/unix Fadvise.
-- 2026-02-12: Optimized file copy for large databases; moved temp
