ci: enforce MISS_HIT complexity metrics and enable more style rules

Add mh_metric --ci to CI workflow with thresholds for cyclomatic
complexity, nesting depth, parameter count, and function length.
Un-suppress 7 low-count style rules and auto-fix violations across
the codebase (whitespace around brackets, semicolons, colons,
assignments, continuations, and operator placement).
