Fixes 11 distinct inline anchor slugs that drifted from the generated
canonical form: em-dash titles render `--` (single-hyphen links were stale),
plus several truncated/old slugs (D-5, D-10, D-21, D-39, D-40, D-43, D-68,
Q-1, Q-32, Q-33). pql resolves cross-refs by ID so these were never "broken"
to the tooling, but they'd fail GitHub markdown anchor navigation. Verified:
every inline anchor now matches the README index; pql decisions sync reports
0 broken refs.
Does NOT touch the separate stale-path class (flat `questions-*.md` /
`rejected.md` naming from before the DQR subdir split) — surfaced for a
follow-up.
