dep(eslint): upgrade to v10

- net: dropped 178 dependencies, added 30
- dropped packages that don't support eslint 10:
  - eslint-config-semistandard
  - eslint-config-standard
  - eslint-plugin-import
  - eslint-plugin-n
  - eslint-plugin-promise
- added @eslint/js, @stylistic/eslint-plugin, globals
- add @Stylistic and rule tweaks to preserve legacy config.
- 3 small lint fixes in packet.js:
  - removed a setter's redundant return
  - removed a useless chunkLength = 0 init
  - removed stale eslint-disable-next-line no-extend-native directives
