Build the current workspace snapshot on native CI runners

This branch snapshots the in-progress desktop workspace so GitHub-hosted Windows and Linux runners can package the same source tree that already passes local verification on macOS.

Constraint: Local Apple Silicon Docker/Wine packaging crashes before Windows artifacts are produced
Rejected: Publish from the incomplete base repo state | remote typecheck failed because current source additions were missing
Confidence: medium
Scope-risk: broad
Directive: Treat this branch as a build snapshot only; do not merge it without reviewing the unrelated workspace changes it contains
Tested: local typecheck, lint, workspace typecheck, unit tests, integration tests, e2e smoke, macOS signed release upload
Not-tested: Native Windows/Linux artifacts before this CI run
