fix(deps): pin tao to the upstream Wayland CSD fix commit

[InstaZDLL]

Summary

• GNOME/Wayland title bar buttons (minimize/maximize/close) are unresponsive on tao < 0.36.0 — a known upstream bug (tauri-apps/tao#1218).
• The fix merged to tao's main branch on 2026-06-29 but hasn't been published as a crates.io release yet (latest published is still 0.35.3).
• Pins tao/tao-macros to the merge commit via [patch.crates-io] (same mechanism already used for the glib 0.18.5 backport, see the existing comment in Cargo.toml) so the fix ships now instead of waiting on an unscheduled tao release.
• This is a temporary pin — documented inline to be removed once tao ≥ 0.36.0 is published on crates.io (tauri's existing ^2.11.4 tauri-runtime-wry range already accepts it, no version bump needed on our side at that point).

Test plan

• cargo check --workspace --all-targets — green
• cargo test --workspace — blocked locally by disk space (unrelated to this change); relying on CI
• Manual: confirm title bar buttons respond on GNOME Wayland once this ships in a build

Closes #427
