Add type annotations to all previously untyped functions and remove 9 suppressed error codes (call-arg, assignment, return-value, operator, has-type, dict-item, misc, list-item, annotation-unchecked) by fixing the underlying type issues. Add [[tool.mypy.overrides]] with ignore_missing_imports for KiCAD-specific modules (pcbnew, sexpdata, skip, cairosvg, kipy, PIL) so the pre-commit mypy hook passes in its isolated venv. Add types-requests and pytest to additional_dependencies in .pre-commit-config.yaml. Also fixes several real bugs uncovered by stricter checks: incorrect static calls to instance methods in swig_backend, wrong return type on get_size, missing value param in BoardAPI.place_component, variable shadowing in kicad_process.py, unqualified LibraryManager reference in kicad_interface, and missing top-level Path import.
