SwiftTUI 0.18.2 fixes collection navigation, input, and rendering

SwiftTUI 0.18.2 brings the recent framework bug fixes to all nine coordinated packages.

Lists recover focus when measured row heights change, multiline table rows retain their geometry, and direct outline lists support native row focus. Thanks to @echoz for these collection fixes in #57.

The release also preserves precise scroll positions and final-row navigation, keeps state and bindings attached to their owners, and reconciles presentation and accessibility focus. Terminal readers share incremental decoding behavior across native, WASI, and Windows hosts, preserve input through probes and handoffs, and protect secure drafts and clipboard access.

Windows image loading preserves Unicode filenames in file URLs, direct paths, and resource-root lookup.

Rendering fixes cover text and glyph boundaries, paths, colors, image sampling, GIF disposal, JPEG orientation, and clipped paint damage. Host corrections improve wire validation, disconnected recovery, custom browser bundle paths, and empty scene manifests in the SwiftUI host.

See the framework release notes and changelog for the full changes.
