Desktop Regular Release

Perform a regular desktop release from the dev branch.

This workflow is now file-driven:

apps/desktop/changelog/next.md is the human-edited changelog draft.
apps/desktop/release-plan.json is the human-edited release intent.
pnpm --dir apps/desktop bump applies both inputs, writes apps/desktop/release.json, resets apps/desktop/release-plan.json, bumps the version, creates release/desktop/{NEW_VERSION}, pushes it, and opens the PR.

Important notes:

mainHash is still regenerated automatically, but it is not the OTA compatibility switch anymore. Do not use it as the release decision point.
runtimeVersion in apps/desktop/package.json is the desktop OTA compatibility key. apps/desktop/scripts/apply-release-config.impl.ts writes it during bump.
This skill covers the normal build and ota desktop release flow.
Do not recommend or write any other mode. The current implementation only supports build and ota.
