feat(eeschema): collab SCH_SHAPE emit + defensive text; defer shape/symbol add (asyncify trap); un-skip apply e2e

- itemToJson hand-maps SCH_SHAPE geometry (SHAPE_T, start/end, arc center,
  bezier ctrl pts, stroke width, fill) for emit + the changed/move path.
- makeItem: parent + default-size SCH_TEXT (mirrors createNewText).
- SCH_SHAPE/SCH_SYMBOL `added` reconstruction deferred: committing a new
  shape/symbol traps in SCH_COMMIT::Push from the programmatic apply context
  (asyncify invoke_* mis-dispatch, not the boundary 'signature mismatch' the
  dyncall shim catches). makeItem returns nullptr -> graceful 'no converter'.
- Un-skipped + extended the headless apply e2e (move via sx/sy line form,
  delete, text-add); apply works headless (old 'Push no-ops' belief was stale).
- features/yjs-bridge/0006: full findings (bugs 1+2 don't reproduce, etc).

No kicad-fork change.
