M2: targen/printtarg workflow, resume, gallery, presets (#7–#11)
Stage 1 targen: typed TargenConfig + argv builder (-v -d 2/4, -f, -e,
-B, optional advanced flags, CMYK-only -l, never -u), ArgyllRunner over
ProcessManager, Stage1View with disk-gated Generate.
Issue 8: Open Existing resume — .ti1 → Stage 2, .ti2 → Stage 3 shell
with persistent "Resumed from .ti2" banner, sibling-.ti1 gate.
Stage 2 printtarg: PrinttargConfig/args (-v -u, -i, -p, -R 1 default,
-r raster, -t/-T DPI), Stage2View with instrument/page/DPI/label
controls, CM warning, stubbed print panel.
Issue 10: pretty-manifest JSON parsing, host-side TIFF→PNG gallery
previews, per-page stubbed print, failure stays on stage.
Issue 11: typed ProfilingPreset schema with legacy CustomPreset
migration, four built-ins, save/manage/import/export UI, DPI binding.
Tests: 124 Core tests (Swift Testing) + 11 Milestone2UITests (XCTest)
with committed fixture sidecars — all green on arm64+x86_64 universal
build. No hardware, no downloads.
Also: ProcessError LocalizedError conformance; accessibilityElement
.contain on container identifiers so child AX ids survive.
