- Added react-ace and ace-builds to optimizeDeps.include
- This forces Vite to properly bundle the CommonJS react-ace module
- Resolves 'Element type is invalid' error when opening files
The react-ace package uses CommonJS exports, and Vite needs to
pre-bundle it to properly handle the default export in ESM context.
1. Vite config: make HTTPS conditional on SSL cert/key files existing
(pre-existing issue, broke builds when certs not present)
2. Drone reconnect handler: use socket.io Manager-level 'reconnect'
event (this.socket.io.on) instead of Socket-level event, and add
explicit type annotation for attemptNumber parameter
