8e24cf48df fix(gbrain): brain context loads, managed sync works, memory sync stops duplicating (#2883, #2985, #2922)
- brain-context-load called 'gbrain list_pages' (an MCP tool name), so
  every skill's brain context was 0 bytes. It now uses 'gbrain list'
  with gbrain's real filter flags, and prints one line when queries fail.
- The code-stage sync always passes --no-pull (managed gbrain >= 0.51
  refuses without it); a gbrain that rejects the flag fails with an
  upgrade message and is never retried without it. stderr is streamed
  with a bounded tail and quoted in failure summaries.
- /sync-gbrain gains --sources (and GSTACK_MEMORY_INGEST_SOURCES); by
  default it skips types already synced through a federated curated
  source, so curated pages stop being re-duplicated.
