fix: v1.1.2 — startup panic from double logger init (closes #2)

egui_logger and tracing-subscriber both tried to install the global log
backend. Only one can exist — the second .init() call panicked with
"Unable to install global subscriber: SetLoggerError(())".

Fix:
- Remove tracing_subscriber::fmt().init() from main()
- Enable "log" feature on tracing crate so tracing::info!/warn!/etc.
  bridge automatically to the log crate that egui_logger owns
- Remove tracing-subscriber dependency (was only used for the init call)

All tracing macros now reach the in-app Logs tab via egui_logger.
No behavior change — log output is identical, panic is gone.

Fixes: #2

+### Fixed
+
+**Startup panic: `Unable to install global subscriber: SetLoggerError(())`**
+- The app crashed immediately on launch with a panic from `tracing-subscriber`.
+- Root cause: `egui_logger::builder().init()` and `tracing_subscriber::fmt().init()`
+  both attempt to install the global log backend. Only one can win — the second
+  call panics unconditionally (no `.ok()` guard).
+- Fix: removed `tracing_subscriber::fmt().init()` entirely. Enabled the `log`
+  feature on the `tracing` crate so all `tracing::info!()` / `warn!()` etc. calls
+  automatically bridge to the `log` crate, which `egui_logger` captures for
+  display in the Logs tab. No separate subscriber is needed.
+- Removed `tracing-subscriber` dependency (was only used for the conflicting init).
