i18n: translation support for command palete

[EriksRemess]

Most obvious next step in translating Ghostty is the command palette.
Added support for i18n.N_ (https://docs.gtk.org/glib/i18n.html#macros).
Made a Latvian translation for the command palette to test. Codex did bulk of the translations but I verified them.

I definitely want more reviewers, but this in general makes sense. I made one note.

It would be nice if Latvian translation updates were done in a separate future PR, since that requires a review from a completely different set of people as the rest of the code and is orthogonal to this PR.

Also, I'm not sure how it's done but I believe you need to update all the other translation files to have the untranslated strings placed in them; other PRs that added translations (e.g. #9976) have done so.

[EriksRemess]

Ok, I'll remove Latvian translation for now. Should I also remove .pot? That is also generated by the same zig build update-translations.

[00-kat]

Definitely keep the .pot changes, having empty strings for the translations is fine; reviewing the translated text themselves is what's problematic (since most maintainers can't review that, so we need to ping the respective localization team).

zig build update-translations

It looks like update-translations itself should do that:

ghostty/src/build/GhosttyI18n.zig

Lines 185 to 190 in c2e9de2

	inline for (locales) |locale| {
	const msgmerge = b.addSystemCommand(&.{ "msgmerge", "--quiet", "--no-fuzzy-matching" });
	msgmerge.addFileArg(b.path("po/" ++ locale ++ ".po"));
	msgmerge.addFileArg(xgettext_merge.captureStdOut());
	usf.addCopyFileToSource(msgmerge.captureStdOut(), "po/" ++ locale ++ ".po");
	}

If it changed every single translation file to add untranslated strings, you should probably git add that.

I guess, test should be retried https://github.com/ghostty-org/ghostty/actions/runs/23306874737/job/67784178019?pr=11641

Thanks!

test should be retried

Done.
