Check the current file against a LanguageTool server (typically a local
instance) from a background thread. Issues are underlined in the editor
(red spelling, blue grammar) and listed in a bottom panel with one-click
fixes that re-align the remaining matches.
A menu bar (File / View / Settings) exposes a LanguageTool settings
dialog with discrete scheme / host / port / token / language fields, an
endpoint preview, and a Test connection button. Config stores the parts
and assembles the base URL. The token is sent as a bearer header.
Uses ureq with a statically-linked rustls backend, so both http and
https endpoints work with no new runtime library dependencies.
