MINOR (F2 review): the module docstring claimed FiscalResult/TributoLinha
'are NOT re-mirrored here' but the file defines FiscalResultPayload/
TributoLinhaPayload right below it. Corrects the prose to describe reality:
they ARE re-mirrored, deliberately kept separate from the lib's own pydantic
classes (this module is the wire contract the service owns), converted via
emission.service._to_fiscal_result/_to_tributo.
