chore(deps): update Action Node.js type definitions

[dependabot]

Summary

Update the GitHub Action's Node.js development type definitions from 24.13.4 to 26.6.3.

Changes

• Update the pinned @types/node development dependency and lockfile.
• Update its undici-types dependency from 7.18.2 to 8.9.0.
• Preserve the Action's Node 24 runtime requirement and public interface.

Testing

• Independently verified publication dates and all four old/new package archive integrity hashes against npm and the lockfile.
• Verified that both packages contain declarations rather than runtime JavaScript and introduce no installation hooks. The minimum TypeScript version remains 5.6, compatible with the existing 5.9.3 compiler.
• Local Action validation and final current-head CI results are recorded in the approval review before merge.

Risk and rollout

This is a major type-definition update, so compatibility is checked with the existing compiler and the Action's Node 24 test environment before merge. Both packages satisfy the existing seven-day cooldown: @types/node 26.6.3 was published September 25, 2026, and undici-types 8.9.0 July 24. No runtime dependency, accepted input, or runtime default changes.

Reviewed the exact head dcd8b1e. Both updated packages satisfy the seven-day cooldown. Verified all four old/new package archive integrity hashes, upstream declaration changes, unchanged TypeScript 5.6 minimum, absence of installation hooks, and compatibility of the Action call sites with Node 24.

Local validation passed on Node 24: clean dependency installation; Action validation including TypeScript 5.9.3 typechecking, 135 tests, metadata, generated documentation, and distribution consistency; published CLI integration; and the packaged Linux dry-run/cleanup smoke test. Current-head required CI passed, and all review threads are resolved. Reviewed the public PR material and artifacts for sensitive information. No compatibility repair was needed.
