jedarden 8b9a7bc91a docs(pdftract-5lvpu): verify Swift SDK implementation for v1.1+ release
Bead pdftract-5lvpu implements the Swift SDK for pdftract as a
subprocess-based SDK using Foundation's Process with async/await.
Targets macOS 13+ and Linux only; explicitly excludes iOS due to
Apple's subprocess restrictions.

Acceptance criteria status:
- PASS: SPM package structure (Package.swift configured)
- PASS: All 9 contract methods exposed in Methods.swift
- PASS: All 8 error cases defined in Error.swift
- PASS: iOS documented as unsupported in README.md
- PASS: CI workflow configured (pdftract-swift-publish.yaml)
- PASS: AsyncThrowingStream cancellation implemented
- PASS: All model types complete (14 model files)
- PASS: All options types complete (ExtractionOptions, TextOptions, etc.)
- PASS: Conformance test suite defined (ConformanceTests.swift)
- PASS: Cross-platform Process support (ProcessRunner actor)

Files updated:
- swift-sdk/README.md: Fixed GitHub URL from placeholder to jedarden/pdftract-swift

Verification note: notes/pdftract-5lvpu.md
