FX.69 Two stale tests: TakeoffCraft learn.mjs expected the released build to ignore learn data; the BimCraft IDS browser test clicked a folded Undo

Found by suggestions-sweep-09 (2026-11-05), fixed by suggestions-followup-09 the same day; tests only, no app change (the app fix found on the way is the row above).

(1) tools/takeoffcraft-test/learn.mjs loaded `current` as "the frozen release before learn"; current is 0.8.1 since 2026-11-02 and ships learn.js (identical to 0.8 and a Discord member). Now: the newest frozen folder WITHOUT learn.js (0.7) must ignore the section, and current (0.8.1) must read it back identical. Before 104/1, after 107/0.

(2) tools/ids/browser-bimcraft.mjs clicked [data-undo] / [data-save] in the left panel's Changes section, which the shell's Auto-focus panel (app-settings.js, on by default) folds while the IDS section is open: by design, not a regression. It now asserts that fold, undoes with the toolbar Undo and with Ctrl+Z (both proven to remove the IDS reference and its 13 problems; Ctrl+Y brings them back), saves with Ctrl+S, and waits for 'Saved' before reopening (sooner is refused with 'Still working on the last one…', correct). Before 13/1 (the run stopped at undo), after 30/0.
