fix(doc-gates): review findings — GitHub-slugger parity and the surviving old-rule prose

ds-review-bot round: slugs now come from RENDERED heading text (links,
inline code, emphasis) with underscores kept and GitHub's occupied-set
repeat suffixes; explicit <a id> anchors register only from real HTML flow
(fences, inline code, and comments no longer produce phantoms); fragment
matching is exact-case since element ids are. anchorCache is exported and
the spec reuses it. The contradicting 'gate checks file existence, not
#anchor validity' sentence in docs/AGENTS.md is gone; the dsh-doc-standards
residual caveat names the real TS-string anchor homes; the 2026-06-18
cross-link note is updated to shipped behavior and cross-linked with the
fragment-gate note.

Scope matches the other gates plus the AGENTS.md pair and the repo-authored agent-skill Markdown under `.agents/skills/` (those skill files cross-link into the docs tree, so this reorg rewrote links in them too): `README.md`, `docs/**/*.md`, `packages/*/README.md`, `AGENTS.md`, `packages/AGENTS.md`, `.agents/skills/**/*.md`, deduped by real path (the `CLAUDE.md` symlinks resolve onto the AGENTS.md files). It is wired into `doc-sync`, so relevant documentation changes and CI exercise the same broken-link check.
This gate checks *existence*, not anchor validity: a link to a real file with a `#wrong-heading` fragment still passes (the file resolves; the fragment is stripped).
The gate now also checks `#fragment` anchors on Markdown targets — same-file anchors included — against heading slugs and explicit `<a id>`; the [fragment-anchor decision](2026-08-09-md-fragment-anchor-gate.md) owns that mechanism and the slug rules.
## Alternatives considered
**Anchor-level validity checking** — heavier and lower-value; file-level dead links are the failure that actually bit. The scope cut is deliberate: authors verify `#fragment` anchors themselves when linking to one.
**Anchor-level validity checking** — deferred here as heavier and lower-value (file-level dead links were the failure that had actually bit), leaving authors to verify `#fragment` anchors themselves. That manual rule did not hold; the [fragment-anchor decision](2026-08-09-md-fragment-anchor-gate.md) later added the check.
