Add AI-powered photo colorization that converts B&W/grayscale images to
full color using DDColor (ICCV 2023 dual-decoder architecture) via ONNX
Runtime. Includes model selection (Auto/DDColor/Classic), adjustable color
intensity, batch processing, before/after preview, and full HEIC/HEIF support.

* feat(image-enhancement): add analysis and correction types
* feat(image-enhancement): implement auto-enhance analysis and correction engine
* test(image-enhancement): add unit tests for auto-enhance engine
* feat(image-enhancement): add API route with analyze endpoint and register in constants/i18n
* feat(image-enhancement): add UI component with mode selector, intensity slider, and analysis badges
* test(image-enhancement): add integration and e2e tests
* fix(image-enhancement): use modulate instead of gamma for exposure correction
Sharp's gamma() only accepts values between 1.0 and 3.0, but brightening
underexposed images computed gamma < 1.0. Switch to modulate({ brightness })
which handles both brightening and darkening correctly.

Add 12 previously undocumented routes to the OpenAPI 3.1 specification:
content-aware-resize, edit-metadata (+ inspect), stitch, pdf-to-image
(+ info, preview), gif-tools/info, remove-background/effects, preview,
pipeline/tools, and pipeline/batch. Fix license from MIT to AGPL-3.0,
correct DELETE /files response from 204 to 200 with body, and update
VitePress API docs (rest.md tool table, ai.md model parameters). Also
register the sharpen operation in the image-engine OPERATION_MAP so it
can be used as a standalone pipeline step.

- Route resize steps with contentAware=true to the content-aware-resize
tool in both single-file and batch pipeline paths
- Update HEIC filename extension to .png after decoding so downstream
tools don't attempt double-decoding
- Wrap per-step errors with step number and tool name for clarity
(e.g. "Step 1 (resize): Resize requires width, height, or percentage")
- Show first file's step-level error in batch failure messages
Reject non-SVG files with a clear error message instead of letting Sharp
fail with cryptic HEIF/corrupt header errors. Applies to both single-file
and batch endpoints.
Add user-configurable DPI (36-1200) and quality (1-100) instead of
hardcoded values. Support avif, tiff, gif, heif output in addition to
png, jpg, webp. Width is now optional, defaulting to SVG intrinsic size
at the given DPI. Generate browser-previewable webp thumbnails for
non-browser formats (tiff, heif). Remove unused _contentType variable.

Switch from manual fetch to useToolProcessor hook for consistency and
batch support. Add scale/custom sizing modes, DPI presets, 7-format
button grid, quality slider, transparent/color background toggle with
preset swatches, and ProgressCard during processing.
- Add clientJobId field support for SSE progress correlation
- Add updateJobProgress calls matching generic batch route pattern
- Use sanitizeFilename() instead of basename() for security
- Map Zod errors to {path, message} format for consistency
- Include errors array in all-failed response body
The generic batch route validates image buffers by magic bytes, which
fails for SVG input. This adds a dedicated /batch endpoint that sanitizes
each SVG individually before conversion, using p-queue for concurrency
and streaming the results as a ZIP with X-File-Results header.
Also extracts shared conversion logic into a reusable convertSvg helper
to avoid duplication between single-file and batch endpoints.
Sharp cannot encode HEVC directly. Use encodeHeic() (same as convert tool)
to go through heif-enc. Also decode HEIF before Sharp for preview generation.
Hoist NON_PREVIEWABLE set to module scope.
Add user-configurable DPI (36-1200) and quality (1-100) instead of
hardcoded values. Support avif, tiff, gif, heif output in addition to
png, jpg, webp. Width is now optional, defaulting to SVG intrinsic size
at the given DPI. Generate browser-previewable webp thumbnails for
non-browser formats (tiff, heif). Remove unused _contentType variable.
Update erase-object pipeline, eraser canvas, and inpainting Python script.
Add LaMa model download script and update Dockerfile for model support.
Update multi-file tool routes for consistency.
Replace the confusing 2-mode smart crop with a clear 3-mode system:
- Subject Focus: Sharp attention/entropy saliency crop with social media presets
- Face Focus: MediaPipe face detection with headshot framing presets
- Auto Trim: Border removal with optional pad-to-square
Adds detectFaces() to AI package, face preset constants, backward
compatibility for old mode names, and comprehensive integration tests.

engine (3.1+ crashes on aarch64 Debian Bookworm)
- Fix text extraction for PaddleOCR 3.4.x result format (rec_texts)
- Add Node.js-level fallback chain (best -> balanced -> fast) when
Python subprocess crashes

TIFF all work transparently
- Implement real auto-detect language using Tesseract multi-lang script
detection (analyzes Unicode ranges for Hangul, CJK, Kana, Latin)
- Default enhance to off (hurts clean digital images)

- Add HEIC/HEIF/AVIF output conversion via Sharp and heif-enc
- Generate browser-compatible WebP preview for non-previewable output formats
- Fix torchvision compatibility shim so Real-ESRGAN actually loads (was silently falling back to Lanczos)
- Fix denoise crash: Image.fromarray() instead of type(img).fromarray()
- Redirect stdout for entire AI pipeline to prevent library messages corrupting JSON output
- Add GFPGAN model download for face enhancement
- Use batch endpoint for multi-file uploads (enables Download All ZIP)
- Fix multi-image: process selected file, not always first

Ultra quality (People only):
- BiRefNet-matting ONNX (928MB) for true alpha matting with per-pixel
transparency on hair wisps and fine edges
- Custom rembg session class, zero new Python dependencies
- Model pre-downloaded in Docker build for immediate availability
Quality tier labels: Fast / HD / Max / Ultra (shorter, fits 4-col grid)
Adds a new "Ultra" quality tier for People subject type that uses
BiRefNet-matting (ONNX, 928MB) for true alpha matting instead of
binary segmentation. Produces per-pixel transparency for hair wisps
and fine edges that standard models miss.
- Custom rembg session class loads BiRefNet-matting ONNX from GitHub releases
- Zero new Python dependencies (reuses existing onnxruntime)

color-effects) into single "Adjust Colors" tool
- Added exposure, temperature, tint, hue, sharpness controls
- SVG filter-based live preview for all adjustments
- Backward-compatible URL redirects from old tool paths
Other fixes:
- Favicon tool: download button instead of auto-download
- Batch processing: HEIC filename extension fix
- File store: processedFilename field for proper batch downloads
