- lib.rs: replaces stub setup with full wiring: loads PatternFile from
config, extracts log_paths, spawns watcher, runs classifier loop in
async task, dispatches MatchedEvents via notify::dispatch
- lib.rs: config Mutex lock uses unwrap_or_else(|e| e.into_inner()) to
recover from poison instead of panicking
- patterns.rs: load() now tries three path candidates in order
(dev-relative, src-tauri-relative, system) before returning bail!
Validation loop (match_text, sources) retained inside candidate loop
