feat: initial release — Dath v0.1.0

CVD colour correction (deuteranopia, protanopia, tritanopia) via LMS
daltonization over any VS Code theme. Contrast comfort modes, warmth
bias, CVD-safe rainbow brackets with shape hints, custom palette slots,
font and spacing overrides, named profiles, interactive panel with live
preview and per-section resets. Non-destructive — works as an override
layer, never touches theme files.

+## [0.1.0] — 2026-05-07
+
+Initial release.
+
+### Added
+
+#### CVD Colour Correction
+
+- LMS daltonization engine based on Brettel, Viénot & Mollon (1997) — zero external dependencies
+- Correction modes: `deuteranopia`, `protanopia`, `tritanopia`
+- Severity slider (0.1–1.0) for partial CVD correction
+- Corrects 185 workbench UI colour tokens (editor, sidebar, tabs, terminal, diff, minimap, and more)
+- Corrects TextMate syntax token colours read directly from the active theme file on disk
+- JSONC comment stripping and `include` chain resolution for theme file parsing
+- Custom palette slots (`custom1`, `custom2`, `custom3`) with per-role colour pickers in the panel
+- Semantic role matching (String, Keyword, Function, Comment, Error, Warning, Added, Deleted, Modified) for custom palettes
+
+#### Visual Comfort
+
+- Contrast modes: `soften`, `warm`, `cool`, `dim`
+- Contrast strength slider (0.1–1.0)
+- Warmth/temperature bias slider (−1.0 to +1.0) for persistent hue tint on top of all corrections
+
+#### Rainbow Brackets
+
+- CVD-safe bracket palettes derived from the Wong (2011) colour palette
+- Per-CVD-mode palettes — automatically matched to the active correction mode
+- Shape hints (underline) via TextMate rules for colour-independent pair identification
+
+#### Font & Spacing
+
+- Font family override — quick picks for OpenDyslexic, Atkinson Hyperlegible, and Lexie Readable
+- Free-text font input — type any font installed on the system
+- Font size override (px)
+- Line height override
+- Letter spacing override (px)
+
+#### Panel
+
+- Live interactive webview control surface — changes apply immediately
+- CVD mode button group (none / deuteranopia / protanopia / tritanopia / custom1 / custom2 / custom3)
+- Severity, contrast strength, and warmth bias sliders with live label updates
+- Contrast mode button group
+- Rainbow bracket and shape hint toggles
+- Font family buttons and free-text input
+- Font size, line height, and letter spacing sliders
+- Per-section reset buttons (CVD, Visual Comfort, Brackets, Font & Spacing)
+- Global reset to defaults
+- Colour correction live preview — before/after swatches for representative theme colours
+- Inline colour pickers on swatches in custom palette mode
+- Bracket palette preview (swatches + live code sample)
+- Profile management (apply saved profiles, save new profiles)
+
+#### Profiles
+
+- Named configuration profiles — save, apply, and delete
+- Three built-in starter profiles seeded on first install: Deuteranopia, Protanopia, Dyslexia Comfort
+- Profiles capture all settings: CVD mode and severity, contrast, brackets, font family, font size, line height, letter spacing
+
+#### Core
+
+- Status bar item — shows active profile or CVD mode, click to open panel
+- Setup wizard (onboarding) — CVD type, contrast preference, rainbow brackets, shape hints
+- Non-destructive operation — writes only to `workbench.colorCustomizations` and `editor.tokenColorCustomizations` overlay; theme files are never modified
+- Fire-and-forget activation to prevent blocking command registration
+- Theme cache with invalidation on theme change
+- Manual colour correction fallback (clipboard copy) when theme file cannot be read
