perf(serve-static): performance optimization for precompressed feature

[usualoma]

• 6a675c3e79877775c9815023a24f30acdcdeba9e : Replace with faster implementation
• 7f58d8f1aaa142b2f475d0bf0acb00bc2bcaf783 : "Content-Type" is appropriate to set only if the file is found
• 9aeb1cd2522522fc821f98c100f6a2f28ce484bb : As I wrote in https://github.com/honojs/node-server/pull/199#issuecomment-2351498366, if the file is not a compressible mime type, it is better not to find a compressed file

The author should do the following, if applicable

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