Add a Vision page, as a proposal for discussion Restates the 2023 refactoring plan (refonte_du_code_de_qelectrotech) as a statement of direction, and says plainly what QElectroTech is not trying to be. Marked as a proposal at the top, not adopted policy, with review invited from the active contributors. If it is adopted, development_roadmap needs updating to match; if it is rejected, the page should be deleted. The core position: QET will not become an EPLAN replacement and should stop being measured against one. Its three defining properties -- a project is one file, it opens anywhere, it is built by the people who use it -- are worth more than feature parity, and a shared database or mandatory central part data would trade them away. Where it differs from the current roadmap is listed explicitly at the end rather than left implied: seven items already delivered since 2023, the SVG element format buying less than it is said to, the SQLite proposal not distinguishing a derived cache from a source of truth, an inverted dependency in the ElementInformation item, and the latest stable release being January 2026 rather than January 2024.
