fix: clarify architecture warning without version

[cnYui]

Fixes #26.

Summary

• update the architecture without version warning so it describes V setup behavior instead of Node.js
• clarify that this path installs V for the requested architecture from the default branch and skips versioned caching
• rebuild the checked-in action output

Verification

• npm test (23 passed, 5 existing Windows baseline failures; the same five failures reproduce on the unmodified 663cc08827d1fc0532ee755b4dedbb183c11d06a baseline)
• npm run build
• npm run lint
• npx prettier --check "**/*.ts"
• npm run package
• git diff --check

Note: npm run format-check is not usable as-is in PowerShell because the single-quoted glob is passed literally to Prettier as "'**/*.ts'". I ran the equivalent double-quoted Prettier command above.

Thanks @cnYui for the improved warning message! This PR and #38 both address the same issue (#26 — Node copy-paste leftover). #38 is more comprehensive as it also fixes the architecture input description in action.yml (#27). I'll merge #38 and close this to avoid duplicate dist/index.js conflicts.
