* feat: Allow Kong to exit with semantic exit codes
At Block, we've instrumented a number of commandline tools and set SLOs on some tools' reliability. To do that effectively, we had to partition usage errors from reliability issues. We looked at [prior art](https://github.com/square/exit?tab=readme-ov-file#reserved-codes-and-prior-art) and, taking inspiration from HTTP, defined [a set of semantic exit codes](https://github.com/square/exit?tab=readme-ov-file#about) in ranges: 80-99 for user errors, 100-119 for system errors.
We've been wrapping errors in `exit.Error` at whatever level of the stack can tell which class an error is and unwrapping them at exit (`os.Exit(exit.FromError(err))`).
This adds support for semantic exit codes to Kong, to `FatalIfErrorf`, which is used internally by `kong.Parse` and often used in Kong applications.
* feat: Exit 80 (Usage Error) when usage is syntactically or semantically invalid
* refactor: Always exit 80 (Usage Error) on a `ParseError` but don't wrap errors from hooks in `ParseError`
* Switch to the standard errors API, that was introduced in 1.13
* Fix linter errors 🤦
* Remove withStackError
* fix: freeze go version to 1.17, since 1.18 introduced generics, which are not supported by linters yet
* fix: freeze go version to 1.17, since 1.18 introduced generics, which are not supported by linters yet
This was breaking UsageOnMissing() when combined with validation of
positional arguments, in that it was allowing positional arguments to be
omitted. It also broke UsageOnMissing() somehow so that it did not work.
Refactors usageOnMissing option to not run parent commands after
printing usage when a child node is missing.
