- Removed `getFreePort` as its use is always a race condition. Change all uses of it to retrive the port after listening - Added `getPortFrom` as a helper function to read a port from a stream - Remove `Cluster.ownerRef` as it is outdated and no longer needed for 5.0 - Remove `Cluster.enabled`, no longer needed because of above - Removed `Cluster.init`, moved its contents into `Cluster.constructor` as nothing in that function is asyncronous. Currently only being run on `main` as a stop gap until `renderer` gets its own version of `Cluster` - Refactored `LensProxy` so as to prevent `pty.node` (a NodeJS extension) being included in `webpack.extension.ts`'s run - Removed the passing around of the proxy port as that can now be accessed from an instance of `LensProxy` Signed-off-by: Sebastian Malton <sebastian@malton.name>
