refactor(daemon): replace daemon-launch.log with electron-log in desktop, remove from CLI/server

The file-based daemon-launch.log was added as temporary instrumentation
for debugging Windows startup. Desktop now logs lifecycle events through
electron-log; CLI and server supervisor drop the launch logging entirely.
