Surface daemon log tails when tools-dev waits for daemon status and add targeted guidance for native Node addon ABI mismatches.
Generated-By: looper 0.0.0-dev (runner=worker, agent=gpt-5.5)
* feat(dev): add desktop tools-dev control plane
* refactor(sidecar): split Open Design contracts
Move Open Design-specific sidecar protocol definitions into @open-design/contracts so sidecar and platform can remain descriptor-driven primitives.
* refactor(daemon): organize package sources
Keep daemon app code, tests, and sidecar entrypoints in separate package directories so each layer can be built and verified independently.
* chore(repo): streamline maintenance entrypoints
Centralize agent guidance by directory and reduce root command chains while preserving the existing build scope.
* docs: translate agent guidance to English
* fix(sidecar): tolerate stale IPC sockets
Remove stale Unix socket files only after confirming no listener is active, so tools-dev can restart after unclean shutdowns.
