Update skills for Handsontable 17.1 and HyperFormula 3.3

[GreenFlux]

Summary

• Bump Handsontable skill to 17.1.0 (May 2026) and HyperFormula skill to 3.3.0 (May 2026).
• Cover new v17.1 features: DataProvider plugin (with code example), Notification plugin, NestedHeaders rowspan, XLSX export, Angular 17–19 wrapper, ExportFile columnHeaders → colHeaders rename.
• Cover new v3.3 features: 20 new functions (count bump), maxPendingLazyTransformations config option, lazy-transformation/undo-redo leak fixes.
• Refresh dist/*-rag.md via build.sh.

As a side effect of check-links --fix-redirects, all HyperFormula doc links migrated from /guide/ to /docs/guide/ to follow the upstream site restructure — that touches every HF reference file but is purely a URL update.

Test plan

• ./scripts/check-links.sh — all links pass (3 initially-guessed v17.1 URLs were replaced with verified paths; non-existent 17.0→17.1 migration guide was dropped)
• ./scripts/build.sh --skip-links — regenerates dist/handsontable.zip, dist/hyperformula.zip, dist/handsontable-rag.md, dist/hyperformula-rag.md cleanly
• Spot-check dist/*-rag.md to confirm new content (DataProvider example, Notification mention, v17.1 changelog block, maxPendingLazyTransformations) is included
• After merge: tag handsontable/v17.1.0 and hyperformula/v3.3.0 to trigger release CI

Note

Low Risk
Low risk: changes are confined to markdown skill docs and regenerated dist/*-rag.md outputs (no runtime code). Main risk is documentation accuracy/URL correctness after large-scale link rewrites.

Overview
Updates the Handsontable and HyperFormula skill documentation to the latest releases (Handsontable 17.1.0 and HyperFormula 3.3.0), including version-pinned CDN guidance and refreshed verification timestamps.

Adds/updates coverage for new Handsontable v17.1 features (notably DataProvider server-side loading with an example, Notification toasts, Angular 17–19 wrapper guidance, XLSX export, and the ExportFile columnHeaders → colHeaders rename) and new HyperFormula v3.3 guidance (function count bump plus the new maxPendingLazyTransformations tuning note tied to leak fixes).

Per upstream doc restructure, rewrites HyperFormula documentation links from /guide/... to /docs/guide/... (and similar API paths), and regenerates the corresponding dist/*-rag.md artifacts to match.
