Readability-only migration of the wherefore/ log to the verdict-led,
scannable style. No decision, rationale, date, tag, supersession link, or
question ID changed in meaning; this is a prose reformat and dash purge.

- Purge em dashes and ` -- ` punctuation from log entries and topics.md
  (replaced with periods, commas, colons, or semicolons). CLI flags such as
  `npm pack --dry-run` and the `-> see <slug>` supersede banners are left intact.
- Make Decisions bullets verdict-led and split compound bullets that fused
  multiple rulings (adr-positioning, dashboard-schema-and-ui, npm-asset-scope).
- Remove inline bold used to fake structure in the rename-to-wherefore
  alternatives list.
- Frontmatter safety: double-quote previously unquoted free-text scalars
  (8 entry titles, all 7 question texts, one resolution) and escape the
  embedded quotes in Q-005 so the dashboard viewer cannot misparse them.

Frontmatter values are unchanged; no file renamed. The dashboard builds
against this directory with no YAML parse error. Body prose in three entries
still references the old hyphenated `superseded-by`/`superseded-date` keys as
historical fact (the underscore-migration record and the schema entries);
those are intentional and were not rewritten. No frontmatter key was
hyphenated, so no key rename was needed.
