fix: log bootstrap errors to daemon.log and add layout debug logging

- Log fatal errors during daemon bootstrap and startup to pino (daemon.log)
  instead of only writing to stderr, which is invisible on Windows desktop
- Delay process.exit to let pino async streams flush
- Make voice MCP bridge script resolution non-fatal (warn + disable instead
  of crashing the daemon)
- Add PASEO_ELECTRON_FLAGS env var for passing Chromium flags on Linux
- Add layout debug logging to AppContainer for diagnosing sidebar issues
