Previously, `removeComments` only stripped a key when the *last* dot-separated segment matched
the comments key. This meant keys like `features.comment.01` (where `comment` is a middle
segment) were never removed by the optimizer.
The fix changes the check from `key.split('.').pop() !== commentsKey` to
`!key.split('.').includes(commentsKey)`, so any segment in the key path can act as the comment
marker.
`removeComments` was extracted into its own `remove-comments.ts` file. This was necessary
because the main `transloco-optimize.ts` imports ESM-only packages (`flat`, `glob`) that cannot
be loaded by Jest in a CommonJS test environment without complex transform configuration.
Isolating the pure function removes that dependency from the test path entirely.
The test executor was also migrated from Karma to Jest (matching `transloco-schematics`), since
this is a Node.js library with no browser runtime dependency.

Fun fact: The word "comment" comes from Latin commentum, but did you know that in Japanese, comments in code are called 「コメント」(komento) — a direct loanword from English? Interestingly, there are over 7,000 languages worldwide, yet only a fraction are commonly supported in i18n frameworks like Transloco! 🌍 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
