Pull the text-selection concern out of ConsoleTab into a focused, ImGui-free
ConsoleSelectionController (console_selection_controller.{h,cpp}). It owns the
anchor/caret state and all the fiddly logic around it: the mouse-drag lifecycle
(beginDrag/updateDrag/endDrag), select-all, range ordering, text extraction over
the visible model, and the index shift applied when the buffer cap evicts lines
from the top.
ConsoleTab now delegates: the four scattered selection fields (is_selecting_,
has_selection_, sel_anchor_, sel_end_) and five helper methods (selectionStart/
End, isPosBeforeOrEqual, getSelectedText, clearSelection) collapse to a single
selection_ member plus a thin selectedText() wrapper. screenToTextPos (still
view-side — it needs the frame's layout) now returns the shared ConsoleTextPos,
so ConsoleTab::TextPos is retired.
The byte-offset / eviction math was previously only reachable through the live
ImGui renderer; it now has direct unit coverage (testConsoleSelectionController:
ordering, drag lifecycle, upward drag, select-all, partial/full/no-op eviction
shift, and filtered extraction). Full-node + lite build clean; ctest green;
source hygiene clean.
