refactor(dcp-for-compaction): migrate from experimental config to hook system

- Add 'dcp-for-compaction' to HookNameSchema
- Remove dcp_for_compaction from ExperimentalConfigSchema
- Update executor.ts to use dcpForCompaction parameter
- Enable DCP by default (can be disabled via disabled_hooks)
- Update all 4 README files (EN, KO, JA, ZH-CN)
