…rallel (#3126) Moves the creative-core pin from bf5426e to 0de5687, the head of core `main` (green, promoted from dev). The range has the resident-rendering speedups from qbtrix/creative-core#620: the batched composite commits without waiting, the resident dirty check is storage identity instead of a pixel compare, and the Float16 tile upload vectorizes. It also has qbtrix/creative-core#626, which repoints the mutation anchor #620 moved. Core range (58 commits): qbtrix/creative-core@bf5426e...0de5687 Core PRs in the range: qbtrix/creative-core#567 qbtrix/creative-core#568 qbtrix/creative-core#569 qbtrix/creative-core#570 qbtrix/creative-core#571 qbtrix/creative-core#573 qbtrix/creative-core#574 qbtrix/creative-core#575 qbtrix/creative-core#576 qbtrix/creative-core#577 qbtrix/creative-core#578 qbtrix/creative-core#579 qbtrix/creative-core#580 qbtrix/creative-core#581 qbtrix/creative-core#582 qbtrix/creative-core#583 qbtrix/creative-core#584 qbtrix/creative-core#585 qbtrix/creative-core#586 qbtrix/creative-core#587 qbtrix/creative-core#588 qbtrix/creative-core#589 qbtrix/creative-core#590 qbtrix/creative-core#591 qbtrix/creative-core#592 qbtrix/creative-core#593 qbtrix/creative-core#594 qbtrix/creative-core#595 qbtrix/creative-core#596 qbtrix/creative-core#597 qbtrix/creative-core#598 qbtrix/creative-core#599 qbtrix/creative-core#600 qbtrix/creative-core#601 qbtrix/creative-core#602 qbtrix/creative-core#603 qbtrix/creative-core#605 qbtrix/creative-core#606 qbtrix/creative-core#607 qbtrix/creative-core#608 qbtrix/creative-core#609 qbtrix/creative-core#612 qbtrix/creative-core#613 qbtrix/creative-core#614 qbtrix/creative-core#615 qbtrix/creative-core#616 qbtrix/creative-core#617 qbtrix/creative-core#618 qbtrix/creative-core#619 qbtrix/creative-core#620 qbtrix/creative-core#621 qbtrix/creative-core#622 qbtrix/creative-core#623 qbtrix/creative-core#625 qbtrix/creative-core#626 Besides the pin: - `project.yml` gets the same revision, as in #3023. - `PhotoWorkspace.residentComposited` syncs a region's layer tiles across the cores (through `PhotoLayerComposite.inParallel`), as the CPU route renders its tiles. Steps keep their order. On a brush frame that crosses two tiles the sync went from about 0.73 ms to 0.39 ms. - `Tests/render-budgets.md` has the new 8K table and says where a resident brush frame's time goes. 8K brush frame, release on the M2 Pro (median of three runs; the Mac was loaded, with another Photo running): CPU 1.0 ms, GPU-resident 1.4 ms (was 1.7). The GPU route is still behind the CPU. Most of what's left is the display into the presenter's texture, which waits about 0.55 ms for the GPU because the presenter draws from its own queue. Full redraw on the resident route is 31 ms (was 35) and the first picture 166 ms (was 192). Checked locally on macOS: `scripts/bump-core`'s steps at 0de5687. `swift build --build-tests` passed. Every `*ModelTests` target passed except four Library wall-clock budget tests (`oneEditOnSixtyPhotosStaysInBudget`, `cullOneWithinBudget`, `beginImportWithinBudget`, `orderRebuildWithinBudget`), which went over in the parallel run on the loaded Mac and pass when run alone. The brush perf suites (PhotoBrushDisplayTests, PhotoBrushLatencyTests, PhotoBrushInkLatencyTests) passed. With the parallel sync on top, `PhotoModelTests` and `PhotoRenderBackendTests` passed (647 tests), and `PhotoRenderBudgetTests` ran in release with `Tests/SuiteUITests/SegmentedTabsTests.swift` set aside, since it doesn't link in release on SDK 27.

dev went red on macOS after the batch that landed #590 and #594. Two fixture lines failed to compile on the macOS runner:
JPEGFixtures.exif: one long+chain of byte arrays timed out the type checker.PNGFixtures.png:extra.joined()andparts.joined()wereFlattenSequence, not[UInt8].Both are now built as typed parts. The bytes are unchanged. Linux was green because its compiler resolved them in time.
Test plan:
swift build --build-testspasses locally; macOS CI is the real check.
