fix(release): prepare v0.5.1 publish

[lostmygithubaccount]

Summary

• track Tauri-generated capability schemas so the app crate packages cleanly
• replace the Rust release publish action with a strict publish/wait loop so failed publishes fail the job
• bump bookmarks to v0.5.1 after the partial v0.5.0 crates.io publish
