Subject: [PATCH] [2.x] fix: Respect global log level in continuous build
 watcher (#8864)

**Problem**
Running `sbt -error ~run` still prints [info] messages from the watcher
("Monitoring source files...", "Build triggered by...", etc). The watcher
creates its logger using only the watchLogLevel setting (default Info),
ignoring the global log level set via CLI flags like -error or -warn.

**Solution**
In Continuous.getCallbacks, take the more restrictive of the watchLogLevel
and the global log level from State when configuring the watcher appender.

Fixes #7355
