chore(release): prepare 1.0.5 stable release

[wgqqqqq]

Summary

• Bump all stable desktop release metadata to 1.0.5, skipping 1.0.4.
• Synchronize Cargo.lock and the release-please manifest.

Notes

• No scripts/release-notes/1.0.5.md in this release. The updater manifest generation already tolerates a missing notes file and falls back to empty notes, so nothing else changes.
• The mobile version group (android / ios / harmonyos at 1.0.0) ships on its own cadence and is intentionally untouched.

Validation

• pnpm run release:version:check
• pnpm run test:release-packaging
• node --test scripts/relay/package-contract.test.mjs
• pnpm run check:github-config
• pnpm run check:repo-hygiene
• git diff --check
