Joao Moura 92d0694a54 feat: automatic root_scope for hierarchical memory isolation
Crews and flows now automatically scope their memories hierarchically.
The encoding flow's LLM-inferred scope becomes a sub-scope under the
structural root, preventing memory pollution across crews/agents.

Scope hierarchy:
  /crew/{crew_name}/agent/{agent_role}/{llm-inferred}
  /flow/{flow_name}/{llm-inferred}

Changes:
- Memory class: new root_scope field, passed through remember/remember_many
- EncodingFlow: prepends root_scope to resolved scope in both fast path
  (Group A) and LLM path (Group C/D)
- Crew: auto-sets root_scope=/crew/{sanitized_name} on memory creation
- Agent executor: extends crew root with /agent/{sanitized_role} per save
- Flow: auto-sets root_scope=/flow/{sanitized_name} on memory creation
- New utils: sanitize_scope_name, normalize_scope_path, join_scope_paths

Backward compatible — no root_scope means no prefix (existing behavior).
Old memories at '/' remain accessible.

51 new tests, all existing tests pass.
