Chiaro 1.0.0

First release.

Added

• Editing. Real RAW decode through Apple's engine, rendered live on the
  GPU with Metal-backed Core Image. Light and color: exposure, contrast,
  highlights, shadows, whites, blacks, temperature, tint, vibrance,
  saturation, a tone curve, and an eight-band color mixer. Color grading by
  tonal zone (shadow/mid/highlight hue and strength, plus balance) and a
  monochrome mixer weighted by the color mixer's luminance values. Portrait
  blur graded in real ƒ-stops from Vision subject masks, person masks, or a
  monocular depth map (Depth Anything V2, downloaded on demand) with a
  movable focus plane inspectable in a 3D scene. Local adjustments: radial,
  linear, and subject masks, each with luminance-range confinement. Detail:
  clarity, sharpening, noise reduction, vignette, and film grain with its own
  coarseness control; RAW files add decode-time color-noise and moiré
  reduction. Crop and straighten with aspect presets, an arc ruler, and a
  one-click headshot crop. Six built-in presets plus user-saved ones, and
  named versions. Adjustments are scrubbed directly on the photo, with a hold
  for before/after.
• Library. Folder-based, no import step. Camera cards read straight from
  the card. A justified gallery grouped by day, plus grid and sortable
  Finder-style list views. Filters, search, and starring to mark and cull
  keepers. Export to full-resolution JPEG, HEIF, or 16-bit TIFF with quality
  and sizing control.
• Non-destructive sidecars. Edits live in a small sidecar file beside each
  photo; the original is never written to. For camera cards, read-only or
  network volumes, and cloud-synced folders (OneDrive, Dropbox, Google Drive,
  iCloud Drive), the sidecar is kept on the Mac instead, in
  ~/Library/Application Support/Chiaro/Sidecars/.
• Agent surface. An MCP server at http://127.0.0.1:24242/mcp, on
  whenever the app runs, with ten tools: list_photos, get_edit,
  set_edit, get_stats, apply_preset, list_presets, set_starred,
  open_photo, get_preview, and export. Chiaro serves its own editing
  skill over the MCP prompts primitive, so a connecting agent can fetch the
  working method, every control's range and traps, and look recipes. A
  status pill shows what a connected agent is doing while it works, and
  soft-locks manual input so the two of you aren't fighting the same slider.
• Start screen. A welcome card on first run; after that, the last edit as
  a hero card, recent edits, recent folders, and any mounted camera card.
• Distribution. A DMG installer, a Homebrew tap
  (arjunphull123/tap/chiaro), and an in-app check against GitHub releases
  that points you at the release page when a newer version is out.
