Export & Share — PDF, Image, JSON, CSV
Production-ready export system with multi-format output (PDF, PNG/JPEG, JSON, CSV), multi-page PDF rendering with metadata, UTF-8 BOM CSV for Excel compatibility, SwiftUI ShareLink integration, temp file lifecycle management, and a unified export manager — all built on ImageRenderer (iOS 16+) with zero third-party dependencies

What it does
Most apps eventually need to let users export their data — as a printable PDF report, a shareable image, a machine-readable JSON file, or a CSV for Excel. Each format has its own quirks:
- PDF requires CoreGraphics context management, page sizing, and metadata injection.
- Image export needs correct scale factors to avoid blurry output.
- CSV must handle UTF-8 BOM for Excel CJK compatibility and escape special characters (commas, quotes, newlines).
- JSON needs consistent date encoding and pretty-printing for human readability.
- Sharing requires bridging exported files to the system share sheet or SwiftUI's
ShareLink. - Temp files accumulate if not cleaned up after sharing.
This module provides a single SWExportManager that handles all four formats, multi-page PDF, PDF metadata, a format-selection share view, and automatic temp file cleanup — using only Apple-native APIs with zero third-party dependencies.
