fix(config): resolve remaining hardcoded paths and improve readability

- Replace hardcoded ~/.ccs in error messages: ccs.ts (lines 83, 151)
  and delegation-handler.ts (line 333) now use getCcsDir()
- Cache repeated getter calls in local vars for readability:
  openrouter-catalog.ts getCachedModels/setCachedModels,
  aggregator.ts getInstancePaths
- Add path.resolve() for CCS_HOME env var consistency with CCS_DIR
