M4: live boolean editing, arc fields, shape builder on strokes, one-sided widths (#111)

Boolean operands are editable in place with live results (per-operand operations, cached prefixes so a drag recomputes from the edited operand up); a Design panel Arc section; the shape builder takes strokes and open paths as outlined areas; variable width points can be wider on one side.

 | Date | Change | Summary |
 |---|---|---|
+| 2026-10-11 | minor | Live boolean editing, Design panel arc fields, the shape builder on strokes and open paths and one-sided variable widths landed (gap 13): Shapes & vector breadth 92% → 97%, ready 66% → 68%, 8–14 h → 1–3 h; feature breadth ~78% → ~79%; ready for real work unchanged (~47%); full parity ~390–745 h → ~385–730 h |
 | 2026-10-11 | minor | Collaboration wording after the collaboration polish: styles, variables, collections, modes and comments created in a live session take ids from their creator's id space (concurrent creations no longer overwrite each other; the server checks it), others' text carets and selections show on the canvas, and typing in a layer someone else is typing in says so; percentages unchanged |
 | 2026-10-11 | minor | Wording only: live sessions (#104), then the browser joining them and `figcraft://` invite links opening the desktop app; percentages and hours unchanged until the next re-measure |
 | 2026-10-10 | minor | Merged main after #101–#103: WASM plugins (plugins area 0% → 35% breadth, 20% ready; ecosystem 5% → 20%) and the multiplayer core without networking (multiplayer 5% → 15% breadth, 5% ready; collaboration 8% → 12%); menu breadth 97.5% → 98.5% (200/203); ready for real work ~46% → ~47%; full parity 420–790 h → 390–745 h; beta 210–380 h → 200–365 h. Fixed the stated weight sums (areas 1–16 sum to 94, total 113; percentages were already computed with those) |
