Completes the English-only standardization for code, comments, scripts and CI templates (UI/CLI-facing strings stay bilingual pt-BR/en, untouched). Covers the remaining crates/, apps/gui/ui/ and apps/gui/src-tauri/ comments, .gitea/ workflow and template comments, .githooks/ hooks, and the scripts/ source comments for the files already renamed in a prior commit (check.sh, generate-logo.py, install-hooks.sh).
