fix(startup): add init logging + fix app_lib → robin_lib in main.rs

- Fix main.rs: app_lib crate name was wrong, should be robin_lib
- Add log::info! on pattern load success/failure — startup was completely
  silent making smoke testing and production diagnosis impossible
- Log pattern count and dual-boot supplement count on load
- Log matched pattern id on every notification dispatch
- These messages appear in ~/.local/share/tech.circuitforge.robin/logs/Robin.log
