chore(memory): Basic Memory trial begins — sync normalization baseline (283 files)

Basic Memory v0.21.6 first sync over the live memory dir (steward-authorized
live-dir trial, Option A 2026-06-06): adds permalink: to frontmatter, refolds
long YAML description lines, strips final newlines. Bodies untouched —
verified via full diff classification. From this commit forward, any diff in
claude/memory shows only what Basic Memory or the session writes.

Trial design: MemPalace untouched as incumbent; git status check on this dir
at every wrap; end-of-day evaluation (recall quality, sync robustness,
rebuild-from-files, malformed-file behavior).

 description: Surfaced 2026-05-03 during _layout.scss SCSS audit — the .wrapper.not-found CSS rule was dead code (no template, no build path, no class application), but ARC genuinely needs a 404 page. Existing content/404.md is Jekyll-era leftover. Need: ARC-voice 404 design + Hakyll build path + template.
