Refactor response parsing, remove legacy clipboard parser, standardize i18n keys, and update application description

- fix translations in `apps/editor/src/commands/select-imported-files-command/select-imported-files-command.ts`
- translations found in `apps/editor/src/features/search-files` should be placed in `apps/editor/src/i18n/translations/features/search-files` under approprite keys, not that those in `apps/editor/src/commands/search-files-commands.ts` should be left intact
- we believe file path parsing is not very robust, e.g. [Fragment] feels hacky
- the 'generic 1' test exists to verify if '...' doesn't break path parsing. You should create a new, minimalistic test that targets this behavior specifically.
- path parsing has issues, e.g. when we already have path, contents of the code block should not be considered [Pasted text]
- is it true we treat text prefixed with '...' as path?
- strip 'diff-' prefix from folder/file names
