* ci: explicitly disable tagalign
Tagalign requires awkward manual formatting and doesn't provide much
value for readability.
* ci: enable mirror linter
mirror warns against certain cases of useless conversion between string
and []byte.
* ci: enable perfsprint linter
This linter encourages replacing several functions from the fmt package
with faster alternatives. While fixing issues, I also added a few
exported error types rather than returning a naked errors.New().
