Reference doc gains a theme key, an Options column, and the e-paper dark-mode
ghosting caveat. The v0.5 spec gets an amendment note superseding the two
reversed "decide-before-build" calls (auto_sync now a set-ahead palette
command; theme shipped early) without rewriting the verified-on-device
history; macroplan updated to match.
Record the d14d9e7 behaviour the doc didn't cover: format-on-save keeps at
most one trailing blank line, and load-verbatim + guarded-save render a
file's POSIX terminator as a visible trailing empty line.
Move each version's scope checklist and status out of the monolithic
macroplan into a dedicated docs/vX.Y-<slug>.md page; macroplan keeps the
source block, the rollup status, and a one-line summary + link per
version. v0.1 reuses its existing product/technical pages.
Also drop the "Optional column ruler at 80" requirement from v0.6.
