Image › Adjustments overhaul: full params, one editor per kind, live-preview dialogs, Curves point deletion (#68)
* Adjustments: full parameter sets for every kind, Hue/Sat ranges, CMYK/Lab tone channels

- doc: Hue/Saturation gains six colour ranges (HueRange), Gradient Map a dither flag,
  Levels/Curves a ToneSpace (RGB, CMYK inks + black, Lab) for mode-native channels.
- engine: new adjust_params module (from_params over a base / to_params) used by
  image.adjustments.*, layer.newAdjustmentLayer.* and layer.setAdjustment. Curves,
  Color Balance, Channel Mixer, Black & White, Gradient Map and Photo Filter now honour
  their params; bad params are BadParams errors; setAdjustment merges (empty = reset).
- compose/gpu: hue-range tables, CMYK/Lab tone channels (CPU; GPU falls back), dithered
  Gradient Map, Black & White from grey/secondary/primary parts; GPU parity extended.
- io: hue2 ranges, grdm dither, CMYK/Lab Levels/Curves records round-trip.
- destructive adjustments use the document's tone transfer.

* Adjustments UI: one editor per kind for Properties and Image › Adjustments dialogs

- adjust_editors: Brightness/Contrast (legacy), Levels and Curves (per channel in RGB, Gray,
  CMYK and Lab, histogram behind), Exposure, Vibrance, Hue/Saturation (master + six ranges with
  draggable range sliders, colorize, before/after spectrum), Color Balance (tones, preserve
  luminosity), Black & White (six weights, tint colour), Photo Filter (presets or colour,
  density), Channel Mixer (outputs, constant, monochrome, total), Posterize, Threshold
  (histogram), Gradient Map (stops, presets, reverse, dither). Replaces the M7 placeholder.
- Properties previews live (GPU) while a control moves and commits one setAdjustment per gesture.
- adjust_dialog: Image › Adjustments opens the same editor modally; the canvas previews the
  real command on the proxy, Preview checkbox, OK = one history step, Cancel leaves the doc.
- Curves (#43): hit-test at the press origin, Delete/Backspace removes the selected point when
  the graph has focus, Cmd/Ctrl-click removes, dragging off removes (and back on restores),
  arrows nudge; endpoints and the last two points stay; pressing the gradient bars does nothing.
- tone: histograms per channel space, of the image below a layer or of the target layer alone.
- kittests: every adjustment layer kind edited through the Properties panel with real input at
  8/16/32-bit RGB, Gray, CMYK and Lab (#12); Curves point interactions; dialog preview/OK/Cancel.

* io tests: adjustment round trip covers the new Levels/Curves/Hue-Sat/Gradient Map fields

#60's round-trip tests predate #68's doc-model additions (tone space and black channel,
Hue/Saturation ranges, Gradient Map dither); fill them with their defaults.
