Vamooses Dye Studio

**Added**
- **Auto-Harmonise** -- pick any dye and Dye Studio now suggests colour
  companions for it: harmonious neighbours, the bold complement, balanced
  triads, and deliberate clashes, plus neutral grounding tones. It works
  wherever you dye:
  - **Colors tab** -- selecting a dye shows a band of harmony swatches beneath
    it, laid over a watercolour wash of that colour so you can judge each
    pairing against the real thing. Click a swatch to jump to that dye.
  - **Live mode** -- a strip of strategy buttons (Neutral, Mono, Analogous,
    Complement, Split, Triad, Clash) fills the decor's other channels around
    your focused channel in one click. A neutral main colour swaps the buttons
    to Tones / Contrast / Accent.
  - **Canvas** -- a "Harmonise" button opens a menu of the same strategies
    (with colour previews) and dresses the previewed decor.
  Every channel gets filled -- a complement on a 3-channel piece, for example,
  adds a grounding neutral so nothing is left blank.
  Under the hood, each dye is placed on a colour wheel by its perceived hue and
  brightness; Dye Studio reads off the classic relationships -- the opposite hue
  for a complement, neighbours for analogous, evenly-spaced hues for a triad, a
  deliberately unrelated hue for a clash -- and picks the nearest match from the
  palette, keeping a brightness gap so pairings read as distinct, not muddy.
  Suggestions are drawn from the 62 in-game housing dyes, so some colours have a
  deeper range than others: a sparsely-stocked hue (pink, say) has fewer shades
  to work with and leans on grounding neutrals to dress a full piece.
- Vamoose's Dye Studio now appears in the minimap's Addon Compartment drawer.
  Click the entry to toggle the window.

**Changed**
- Colours-tab dye rows are now click-to-select: the detail panel stays on the
  dye you click instead of following the cursor as you move toward it.
- The Live action bar is reorganised -- Apply is now larger and on the left
  (the primary action), then Revert and Snapshot, with the Owned-only toggle on
  the right. The "+N dyes" cost readout was removed; instead, the Apply tooltip
  now lists the exact dyes (and how many of each) a commit will consume.
- The live editor's channel rows are tighter, and the "Slot 1/2/3" labels were
  dropped -- hovering a channel already names it and its dye, so the numbers were
  redundant.

**Fixed**
- Canvas: for decor whose dye channels skip the first one, clicking a dye now
  lands on the first channel the item actually has instead of being applied to
  an unavailable channel (where it appeared to do nothing).
