chore: roll Rust deps to current compatible majors

[yvette-carlisle]

Summary

• roll the Rust workspace to the latest compatible direct and transitive dependency set
• migrate the egui/wgpu rendering paths needed for egui 0.34 and wgpu 29
• treat surface Timeout and Occluded as skip-frame conditions instead of fatal overlay errors

Dependency updates

• egui 0.33 -> 0.34
• egui-phosphor 0.11 -> 0.12
• egui-wgpu 0.33 -> 0.34
• egui-winit 0.33 -> 0.34
• wgpu 27 -> 29
• tray-icon 0.21 -> 0.22
• toml 1.0 -> 1.1
• criterion 0.7 -> 0.8 in both workspace crates
• regenerate Cargo.lock

Verification

• cargo make fmt-rust-check
• cargo make fmt-toml-check
• cargo make lint
• cargo make test

Notes

• this covers the current open Dependabot bumps for wgpu, egui-winit, xcap, tracing-subscriber, and criterion
• no docs changes were needed; release-tag packaging workflows were not affected
