* Test coverage hardening and parallel-safe refactors
Add focused test coverage for under-tested operational paths, edge branches,
and make key table-driven suites parallel-safe. Also fixed flaky installer
test execution under repeated/parallel runs.
* chore: fix goimports ordering for golangci-lint
* Test(download): expand integration coverage for download paths
Add integration scenarios for force/pull repo updates, repo-only and skip semantics,
and direct AUR download/scanner coverage used by getpkgbuild and package preparation.
* Test(exe): relax systemd-run path assertion
Fix flaky TestBuildGitCmd by accepting an absolute systemd-run path while still
asserting the expected binary is used.
* Test(text): avoid race in color tests
Remove parallel execution from TestColorHash so global UseColor writes do not
overlap with color consumers in parallel tests and trigger race detector
failures.
* fix potential race conditions
* rework relationship between runtime and cfg
* separate runtime from cfg
* simplify instantiation logic
* move installer to appropriate package
* move operator to sync package
* add tests for srcinfo service
* consolidate srcinfo service in sync
* add logger to srcinfo
* add logger to preparer
* remove unused text functions
* remove remaining text.* from srcinfo
* remove global logger parts
* remove global org method exports
* remove global logger
* move text->input
* add rule to prevent fmt.Print
* update golangci go version
* remove outdated FAQs
* remove outdated FAQs
* add missing locales
* use t.Setenv instead of os.Setenv for tests
* locale: present y/n if localisation is not latin. Always accept y/n in every case
* question: use operation info for question
* edge case where localised n is equal to default y
* add tests for basic locales
