TiaCommander — MCP Server for Siemens TIA Portal

New in this release: a new technology_objects tool — 15 actions for listing and reading technology objects, changing parameters, structural edits, export/import, and connecting an object to its hardware; per-project PLC credentials with a new Credentials tab in the Manager — a project's own password is tried first, a global one is the fallback; transactional block overwrites — the block is exported before the import and restored if the import fails, and overwrites no longer lose attributes, block numbers or folder placement; and compiler results that list only real diagnostics, so totals always match the compiler's own count. Dozens more fixes and improvements since v3.15.2 — see CHANGELOG.md for the full list.

\V17 through V20 are supported for project work. V16 and older are detected and refused with a clear message. Only V19 is fully tested; the others are expected to work as TIA Portal maintains backward-compatible Openness APIs across versions.*
