chore: upgrade golancgi-lint to 1.18.0

New linter 'funlen' was disabled as too many functions break the default
limit, but might be considered for the future.

To limit peak memory usage, `GOGC=50` was added to the golangci-lint run
to make Go's garbage collector more aggressive. With this setting peak
seems to be around 8Gb.
