[Build] Sync GPUI to 24cfa81

[BumpyClock]

Description

Update GPUI from 510dedc3b44fcf80c791ab17e59530ae66e80558 to 24cfa81ca2a9f954b96320e14b393dd519078618 and keep the workspace dependency pins, lockfile, and vendor/gpui submodule in sync.

This also applies the compatibility changes required by the newer GPUI API:

• pin Rust 1.95, which is required by GPUI's std::hint::cold_path usage;
• pass explicit 1.0 grow/shrink factors, preserving the former zero-argument behavior;
• migrate AnyView to into_any_element();
• update WebView entity updates and import FluentBuilder explicitly.

How to Test

• cargo fmt --check
• cargo build --locked
• cargo clippy --locked -- --deny warnings
• CARGO_BUILD_JOBS=2 cargo check --locked -p webview --all-targets --all-features
• cargo metadata --locked --format-version 1

Checklist

• I have read the contributing and repository instructions.
• Reviewed the changes and verified the GPUI API migrations against the old and new implementations.
• Passed cargo run for story tests related to the changes — not run; this is a dependency/build compatibility update with no visual behavior change.
• Tested macOS, Windows and Linux platform performance — not applicable; CI provides cross-platform compilation coverage.

Review Notes

The lockfile intentionally includes GPUI's move from the WGPU git revision to crates.io WGPU 29.0.4. Existing fork-specific overlay and blur behavior remains in the pinned GPUI revision.

Walkthrough

The PR updates the pinned GPUI revision and Rust toolchain, makes flex sizing explicit across UI components, and aligns render and fluent-builder API usage in the field, webview, and example code.

Changes

GPUI update

Layer / File(s)	Summary
Dependency and toolchain synchronization Cargo.toml, vendor/gpui, rust-toolchain.toml	GPUI dependency revisions and the vendored subproject are updated, while Rust 1.95.0, rustfmt, and clippy are configured.
Explicit flex sizing crates/ui/src/dock/tab_panel.rs, crates/ui/src/input/state.rs, crates/ui/src/list/list.rs, crates/ui/src/resizable/panel.rs, crates/ui/src/table/state.rs, crates/ui/src/tree.rs	UI containers and spacers now pass explicit 1. growth or shrink factors to flex layout helpers.
Render API alignment crates/ui/src/form/field.rs, crates/webview/src/lib.rs, examples/webview/src/main.rs	Field rendering uses into_any_element(), webview parent updates are called directly, and the webview example imports fluent builder methods.
