fix: add explicit breaking change rule to semantic-release config

The conventionalcommits preset releaseRules were overriding the
default BREAKING CHANGE: → major mapping. Add explicit rule.

BREAKING CHANGE: DfeMetrics::register() now requires &MetricsManager
parameter. AdaptiveWorkerPool is the new internal vertical scaling
module, bounded and throttled by available CPU and memory.
