chore(release): prepare v1.0.2 — polish patch

Four small backlog items bundled:

- New: hide chat (and every other plugin window) while the New Game+
  menu is open. Settings -> Window -> Frame, default off. Skips the
  whole WindowSystem.Draw() pass while QuestRedo is visible, mirroring
  the existing HideInLoadingScreens pattern.
- New: tint the channel selector button in the active channel colour.
  Settings -> Appearance -> Colours, default on. Reuses the existing
  inputColour computation (incl. ExtraChat override) and adds an
  ImGuiCol.Button push around the selector. New ColourUtil helper
  AdjustBrightness derives hover/active variants.
- Fix: PayloadHandler.InlineIcon hardcoded all hover icons to 32x32.
  Replaced with float-based aspect-ratio-preserving shrink, single
  scale-factor, zero-size guard, named MaxInlineIconSize constant.
  Affects six call sites (status, item, achievement and other inline
  hover paths).
- Diagnostic: HideState transitions log on Verbose level for both
  ChatLogWindow and Popout.

Manifest bumped to 1.0.2 across csproj, yaml, repo.json. CHANGELOG
entry added, README version line updated. yaml + repo.json changelog
trimmed to the slim 4-version window (1.0.2, 1.0.1, 1.0.0, 0.6.1).
