fix(dump-autoload): add config defaults, CLI validation, and class count output

Read optimize-autoloader, classmap-authoritative, apcu-autoloader from
composer.json config section. Reject --dev with --no-dev and --strict-psr/
--strict-ambiguous without --optimize. Emit pre/post generation messages
with class count in optimized mode. Track ambiguous class mappings and
exit with code 2 when --strict-ambiguous detects conflicts.
