alonso.torres 188dac5ad3 🐛 Skip numerically equal component sync writes
Compare integer and floating forms exactly for scalar values, points and
selection rectangles. A library update that only changes their numeric
representation must not create changes or an undo entry. Preserve every
nonzero difference, including real subpixel moves.

Add the reduced resize/library-sync regression and a subpixel control,
plus async frontend undo/redo replay. Review and update eight golden
states in case N: only equal integer/float representations changed.
The recreated seed-712 audit leaves all 61 syncs and undo depths unchanged.

Common JVM 1,914 tests/31,146 assertions and JS 1,845/29,810 pass.
Frontend 1,563/10,880, its added replay, backend 1,610/8,104 and exporter
14/32 pass. Lint and formatting pass. Exporter needs its test-only secret.

Benchmark ratios against the unchanged baseline: mains 10/100/1000
0.54/0.61/0.61, levels 0.53, chain 0.55, library 0.55, many shapes 0.62,
variant switch 0.65. No regression flag.
