Update Handsontable skill for v18.0

[GreenFlux]

Summary

Bumps the Handsontable skill from 17.1 to 18.0 (released June 30, 2026 — TypeScript core rewrite, new layout system, several removals). HyperFormula skill is untouched — no paired HF release.

Every API detail below was cross-checked against an authoritative source (migration guide, changelog, blog, docs deep-link, or handsontable@18.0.0 on the npm registry). No fabricated shapes.

v18 changes reflected in the skill

• Version + wrappers: 17.1.0 → 18.0.0, CDN pin @17.1 → @18.0, Angular support 17–19 → 16–22
• Cell types: legacy date/time removed → intl-date/intl-time with Intl.DateTimeFormat-shaped options and ISO 8601 source data
• Numeric formatting: numericFormat.pattern/culture (numbro) removed → Intl.NumberFormat options + locale
• HyperFormula: unbundled (handsontable@18.0.0 ships with dependencies: {} per npm registry) — install separately
• DataProvider: re-added filters to fetchRows destructure — the v18 docs explicitly show it, unlike v17.1
• New Layout section: documents the layout option ({ top?: string[], bottom?: string[] })
• Common Pitfalls: refreshed for v18 removals — DOMPurify (need custom sanitizer), legacy date/time cell types, numbro numeric format, handsontable/common subpath, hot.undo()/hot.redo(), PersistentState, DOM wrapper CSS changes, --ht-wrapper-* CSS variable renames
• Version Awareness: new v18.0 breaking-changes block above v17.1; added 17.1 → 18.0 migration link

Incidental fixes

• Vue 3 install URL (pre-existing 404 in docs-map.md and SKILL.md): /docs/react-data-grid/vue3-installation/ → /docs/vue-data-grid/installation/
• Blog release-notes URL (pre-existing 403): /blog/categories/release-notes → /blog/?category=release-notes
• scripts/check-links.sh: ALLOWLIST_403 changed from single fixed string to alternation regex so it can cover both npmjs.com and handsontable.com/blog (both real, both reject the bare UA)

Test plan

• ./scripts/check-links.sh — all 234 links pass
• ./scripts/build.sh --skip-links — dist/handsontable-rag.md (44K) rebuilt cleanly; dist/hyperformula-rag.md unchanged
• Human spot-check that:
  • the new intl-date example matches the migration guide
  • the DataProvider filters re-add is worth doing (v17.1 review had opinions here)
  • the layout option code example is faithful to the v18 docs
• After merge: tag handsontable/v18.0.0 to trigger the per-skill release workflow

Low Risk
Documentation-only changes to skill markdown and a link-checker allowlist; no application runtime code.

Overview
Bumps the Handsontable agent skill and mirrored dist/handsontable-rag.md from 17.1 to 18.0, so guidance matches the June 2026 release.

Version & install references now point at 18.0.0, CDN pins @18.0, Angular 16–22, and the corrected Vue 3 docs URL.

Breaking v18 behavior is documented throughout: intl-date / intl-time and Intl-based numeric columns (replacing legacy date/time and numbro pattern/culture), separate HyperFormula install, optional sanitizer after DOMPurify removal, UndoRedo instead of hot.undo()/hot.redo(), removed PersistentState and handsontable/common, and wrapper DOM/CSS token changes. New sections cover the layout slot ordering API and an expanded DataProvider fetchRows example that includes filters.

references/docs-map.md is aligned to 18.0 (migration link, layout API, intl cell-type notes, CodeSandbox version query params, blog URL fix). scripts/check-links.sh treats handsontable.com/blog 403s like npmjs when using the link checker regex allowlist.

@qunabu @sl01k could one of you review the diff on this update to the Handsontable skill please?

I have a script that has checked all the links for 404's so don't worry about that. Just check that the updated text is accurate.
