refactor(theme): split per-preset color schemes into theme/presets/ (#594)

* refactor(theme): split per-preset color schemes into theme/presets/

Move each ThemePreset's ColorScheme + status colors into its own file under
theme/presets/ (Default, Monochrome, Gruvbox, Catppuccin, Amoled, NeonNoir).
Theme.kt becomes a thin dispatcher via resolveColorScheme/resolveStatusColors,
making individual themes far easier to create and edit.

- AMOLED keeps a dark-only scheme (falls back to default light)
- MONOCHROME/AMOLED reuse default status colors (no bespoke semantic set)
- aligned to current Voltage Purple palette + on* status-color params

Verified: ktlint clean, compileDebugKotlin passes.

* refactor(theme): make all preset files uniform 4-token shape

Every preset file now exports XxxDarkColorScheme / XxxLightColorScheme /
XxxDarkStatusColors / XxxLightStatusColors so they share one shape and import
order. MONOCHROME + AMOLED alias the default status colors; AMOLED also gets an
explicit AmoledLightColorScheme = DefaultLightColorScheme alias.

Theme.kt dispatcher is now a pure lookup (no special-casing) for both color
scheme and status colors. No runtime behavior change — pure structural cleanup.

Verified: ktlint clean, compileDebugKotlin passes.

* docs(theme): add THEMES.md documenting the per-preset convention

Co-located in theme/ — covers layout, the uniform 4-token shape, the pure
lookup dispatcher, why DEFAULT uses design tokens (intentional, not a bug),
and a step-by-step 'add a new theme' recipe.

Verified: ktlint clean.

+# Themes
+
+How theming works in Hermes Control, and how to add or edit a theme.
+
+## Where themes live
+
+All theme code is under:
+
+```
+app/src/main/java/com/m57/hermescontrol/theme/
+├── Theme.kt                       # dispatcher — resolves scheme + status colors per preset
+├── Color.kt                       # brand design tokens (DarkSurface, HermesPurple, StatusGreen, …)
+├── HermesStatusColors.kt          # semantic status color model (success/warning/error/info + on*)
+├── Type.kt / Shapes.kt            # typography + shape tokens
+├── Spacing.kt / Motion.kt         # spacing + motion tokens
+└── presets/                       # one file per ThemePreset
+    ├── DefaultScheme.kt
+    ├── MonochromeScheme.kt
+    ├── GruvboxScheme.kt
+    ├── CatppuccinScheme.kt
+    ├── AmoledScheme.kt
+    └── NeonNoirScheme.kt
+```
+
+## The 4-token shape
+
+Every file in `presets/` is uniform — it exports the same four tokens:
+
+| Token | Type | Purpose |
+|-------|------|---------|
+| `XxxDarkColorScheme` | `ColorScheme` | dark-mode Material 3 scheme |
+| `XxxLightColorScheme` | `ColorScheme` | light-mode Material 3 scheme |
+| `XxxDarkStatusColors` | `HermesStatusColors` | dark semantic status colors |
+| `XxxLightStatusColors` | `HermesStatusColors` | light semantic status colors |
+
+A preset with no bespoke status set (MONOCHROME, AMOLED) aliases the defaults:
+
+```kotlin
+val MonochromeDarkStatusColors = DefaultDarkStatusColors
+val MonochromeLightStatusColors = DefaultLightStatusColors
+```
+
+AMOLED has no bespoke light scheme, so it aliases the default light scheme too:
+
+```kotlin
+val AmoledLightColorScheme = DefaultLightColorScheme
+```
+
+## The dispatcher
+
+`Theme.kt` is a **pure lookup** — no special-casing. Given a `ThemePreset`
+and a dark flag, it returns the matching scheme/status from the preset file:
+
+```kotlin
+private fun resolveColorScheme(preset: ThemePreset, darkTheme: Boolean) = when (preset) {
+    ThemePreset.DEFAULT -> if (darkTheme) DefaultDarkColorScheme else DefaultLightColorScheme
+    ThemePreset.MONOCHROME -> if (darkTheme) MonochromeDarkColorScheme else MonochromeLightColorScheme
+    // …one line per preset…
+}
+
+private fun resolveStatusColors(preset: ThemePreset, darkTheme: Boolean) = when (preset) {
+    ThemePreset.DEFAULT -> if (darkTheme) DefaultDarkStatusColors else DefaultLightStatusColors
+    // …one line per preset…
+}
+```
+
+Dynamic (Material You) color on API 31+ overrides the resolved scheme when
+`useDynamicColors = true`.
+
+## DEFAULT uses design tokens — that's intentional
+
+`DefaultScheme.kt` imports ~47 named tokens from `Color.kt`
+(`DarkBackground`, `HermesPurple`, `StatusGreenContainer`, …) and builds its
+schemes from them. This is **by design**: DEFAULT is the brand reference theme,
+so a palette change in `Color.kt` flows straight through.
+
+The other presets are hand-authored community palettes and use **raw hex**
+(`Color(0xFFFE8019)`), so they only import `Color` (+ `HermesStatusColors`).
+Do **not** "fix" DEFAULT to raw hex to match them — that would break the token
+linkage. The asymmetry is semantic, not sloppy.
+
+## Adding a new theme
+
+1. **Create** `presets/<Name>Scheme.kt` exporting the 4 tokens:
+   ```kotlin
+   package com.m57.hermescontrol.theme.presets
+
+   import androidx.compose.material3.darkColorScheme
+   import androidx.compose.material3.lightColorScheme
+   import androidx.compose.ui.graphics.Color
+   import com.m57.hermescontrol.theme.HermesStatusColors
+
+   val MyThemeDarkColorScheme = darkColorScheme(/* … */)
+   val MyThemeLightColorScheme = lightColorScheme(/* … */)
+   val MyThemeDarkStatusColors = HermesStatusColors(/* … */)
+   val MyThemeLightStatusColors = HermesStatusColors(/* … */)
+   ```
+2. **Add 2 lines** to each `when` in `Theme.kt` (`resolveColorScheme` +
+   `resolveStatusColors`), importing the new tokens at the top of the file.
+3. **Add the enum entry** `MY_THEME` to `ThemePreset` in `Theme.kt`.
+4. **Wire the UI**: add the label + selection in
+   `ui/settings/components/AppearanceSection.kt` (and any string resource).
+5. **Verify**:
+   ```bash
+   ./ktlint --format app/src/main/java/com/m57/hermescontrol/theme/presets/<Name>Scheme.kt
+   ./gradlew compileDebugKotlin
+   ```
+
+## Conventions
+
+- ktlint 1.2.1 is enforced in CI. Run `./ktlint --format` before committing.
+- Import order is ASCII-lexicographic (uppercase before lowercase).
+- Every change goes through a PR — never push directly to `main`.
