fix: coalesce background thread runtime work

[originalix]

Summary

• Coalesce Android cross-runtime SharedRPC executor work into per-runtime queues.
• Return schedule failures from Kotlin so native pending work can be cleaned up instead of leaking.
• Bump all native module/view package versions to 3.0.63, matching the existing app-modules full-package release convention.

Validation

• PATH=/Users/leon/.nvm/versions/node/v22.20.0/bin:$PATH yarn workspace @onekeyfe/react-native-background-thread typecheck
• PATH=/Users/leon/.nvm/versions/node/v22.20.0/bin:$PATH yarn workspace @onekeyfe/react-native-background-thread prepare
• PATH=/Users/leon/.nvm/versions/node/v22.20.0/bin:$PATH yarn workspace @onekeyfe/react-native-background-thread lint
• Confirmed all 33 native module/view packages are set to 3.0.63.
• Confirmed npm has no existing 3.0.63 version for the 33 packages before publishing.
• Built Android prod release APK in x-app-monorepo with the patched module.
• Installed release APK on Pixel 5 and verified cold start -> Perps/合约 -> Swap/交易 no longer white-screens.

Notes

• @onekeyfe/react-native-background-thread@3.0.62 was published by an earlier single-package attempt, but this PR now follows the repo convention and publishes the full package set as 3.0.63.
• x-app dependency bump should consume 3.0.63 after this package-publish run succeeds.
