* perf: switch nearly all remaining uses of stdlib regexp to wasilibs/go-re2 * perf: upgrade github.com/wasilibs/go-re2 from v1.9.0 to v1.12.0 * gofmt modified files * snowflake detector: hoist constant regex compilation to package-level variables * add golangci lint to steer folks to go-re2 instead of regexp
