Wire up internationalization for the app and ship six translations.
Infrastructure:
- meson: import i18n, define GETTEXT_PACKAGE/GSR_LOCALEDIR, add po/ subdir,
and translate the .desktop and AppStream metainfo via i18n.merge_file
(renamed to .desktop.in / .metainfo.xml.in).
- main.c: setlocale + bindtextdomain/textdomain so the catalog is loaded.
- po/: LINGUAS, POTFILES.in, meson.build (glib preset).
String marking:
- Wrap every user-visible string with _() across main.c, gsr-window.c, the four
pages and the shortcut dialog (titles, subtitles, labels, buttons, combo
display names, notifications, toasts, dialogs, menu items).
- Leave ids/keys untranslated: codec/container/service ids, GAction/icon/CSS
names, GVariant/format strings, accelerators, etc.
Linting:
- Re-enable gobject-linter's untranslated_string rule (now that i18n exists) as
an error so new user-visible strings must be wrapped.
Translations (141 messages each, %s/%d/markup placeholders preserved):
- Vietnamese (vi), German (de), French (fr), Italian (it), Spanish (es),
Portuguese (pt). Codec names, "OK", proper nouns and the product name are
intentionally left in English. Verified: msgfmt --check-format passes and the
compiled catalogs resolve (e.g. "Record" -> "Ghi hình" / "Aufnahme" /
"Enregistrement").

Add gobject-linter (github.com/bilelmoussaoui/gobject-linter) to CI to catch
GObject/GLib correctness and idiom issues.
Config (gobject-linter.toml):
- min_glib_version = 2.80 (libadwaita >= 1.8)
- default_level = error: every enabled rule blocks CI
- type_style ignored: the project deliberately uses plain C scalar types
- untranslated_string ignored: app is not internationalized yet
- use_auto_cleanup downgraded to warn: it mis-fires on floating GVariant
references (consumed by g_variant_new_tuple/builders) and on objects kept
alive past the function (the GlobalShortcuts GDBusProxy); converting those to
g_autoptr would over-unref and crash, so it advises rather than blocks
Workflow (.github/workflows/gobject-linter.yml): runs the official container
image on push/PR, uploads SARIF to code scanning (non-fatal for fork PRs), and
fails the build on any error-level finding.
Code is brought to a green baseline by applying the auto-fixable findings:
- strcmp -> g_strcmp0 (NULL-safe)
- manual g_free/g_strdup -> g_set_str
- manual source removal -> g_clear_handle_id / g_clear_object / g_clear_pointer
- g_string_free(.., FALSE) -> g_string_free_and_steal
- g_idle_add one-shot -> g_idle_add_once (id now stored and cleared in finalize,
also closing a latent use-after-free if the window is finalized first)
- include ordering and #pragma once
The 37 remaining use_auto_cleanup findings are reported as warnings for
incremental manual review.
