Add StartConfigWatcher in internal/config/watch.go. It takes a slice of WatchedFile values, each with a Path func and an OnChange callback, and polls them once per second. When a file is modified or the resolved path changes the callback fires. Callbacks run on a background goroutine — callers dispatch to the main thread via timerChan. Wire up three watchers in cmd/micro/micro.go: - colorschemes/<name>.micro → InitColorscheme + Redraw - settings.json → ReadSettings + InitGlobalSettings + Redraw - bindings.json → InitBindings This lets any external tool (theme managers, dotfile syncing, etc.) update micro's config files while the editor is open and have the changes applied immediately without a restart. No new dependencies.

Add `StartConfigWatcher` in `internal/config/watch.go`. It accepts a slice of `WatchedFile` values — each with a `Path` func and an `OnChange` callback — and polls them once per second. When a file is modified or the resolved path changes, the callback fires on a background goroutine. Callers dispatch to the main thread via `timerChan`.
Wire up three watchers in `cmd/micro/micro.go`:
Why: Any external tool (theme managers, dotfile syncing, live config editors) can now update micro's config files while the editor is running and have the changes applied immediately — no restart required. The `Path` func is re-evaluated each tick, so switching colorschemes mid-session is also handled correctly.
Threading: all callbacks run on a background goroutine and post to `timerChan`, keeping every UI mutation on the main thread.
No new dependencies.
