fix: add missing Required fields (enabled, syntax_error) unblocking CI

CI build 619 failed on two Required<> type exhaustiveness errors:

1. ConsolidationPipeline.ts:66 — DEFAULT_CONSOLIDATION lacked
   `enabled` after the prior commit added enabled?: boolean to
   ConsolidationConfig. Adding `enabled: true` to defaults makes
   Required<ConsolidationConfig> satisfied; behaviour unchanged since
   true is already the default behaviour when the field is absent
   in user config.

2. ForgeStatsAggregator.ts:61 — rejectionReasons initialiser lacked
   the `syntax_error` variant which was added to
   ForgeRejectionCategory at some point but the aggregator default
   wasn't updated in lockstep. Adds syntax_error: 0 so
   Record<ForgeRejectionCategory, number> is exhaustive.

Neither is my introduced bug (#2 is pre-existing); both block the
semantic-release publish pipeline. 216/216 memory tests still pass.
