gui_toolkit 0.70.0

Changed

• ui.build_events: a copy of the last build's input, kept by the state until the next build (it was the caller's slice, valid until its next poll).
• Built with Odin dev-2026-11 (pinned by SHA-256 in the CI, docs/getting-started.md): core:image's pixels are a [dynamic]u8, nothing keeps a reference to a stack past its procedure (the compiler's new escape analysis: the tests' globals are cleared, ui.use keeps the caller's state on purpose), core:compress/deflate checks flate's streams in the tests and docs/flate.md compares both (flate stays for streams and deflate_runs). wgpu-native stays 29.0.1.1.
