chore: sync tauri-runtime-cef from upstream feat/cef

[github-actions]

Automated sync from tauri-apps/tauri feat/cef branch.

If this PR has merge conflicts, the upstream changed runtime.rs or webview.rs in a way that requires manual porting of the overlay modules. Fix conflicts and merge.

Before merging, read the divergence report below. Re-applying fork patches by hand is how upstream fixes get dropped silently — the report is the only place they surface, because the copy overwrites the evidence.

CEF version: check the cef pin in Cargo.toml, bump Sable's src-tauri/Cargo.toml to match.

Note: if syncing from amr/cef-gtk4, the Cargo.toml will reference gtk4 and winit-gtk4, the fork's overlay config may need updating to handle the gtk4 crate name and the winit git dep.

Not in upstream, so they survive the copy and never show in this PR's diff.

Upstream items not present in the fork (233)

Each is either a deliberate fork removal or an upstream fix a previous sync dropped. Deliberate removals in this repo always carry a comment explaining why — an entry you cannot find a rationale for is a regression.
