perf(router): improve performance of router

[EdamAme-x]

router performance improvements

Explicitly cached lengths, adjusted the order of evaluation of logical expressions, (without regexp router, for readability)
and removed debugging properties to speed up and use other unique values. (trie-router)

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code

Hi @EdamAme-x, Thank you!

The performance difference between "for-of" and "for loop" is currently quite small (depending on the runtime), so I don't think it needs to be actively rewritten.

However, looking at the benchmarks for loops, it seems that "for loop" is still the fastest, so the changes in this pull request are reasonable 👍
