Scott Idem 49123cdd5c feat: per-role tool lists and system prompt overlays ...

Each role in model_registry.json can now carry two optional keys:
  system_append — injected into the system prompt at position 7 (after
                  memory, closest to the turn) for the active chat_role
  tools         — explicit tool allow-list; intersected with the user's
                  access-level filter so it can only restrict, never elevate

No changes needed for existing users — missing keys fall back to current
behavior. Add keys to a role to give it a specialty focus:

  "coder": {
    "primary": "claude_cli",
    "system_append": "You are in code-specialist mode...",
    "tools": ["web_search", "file_read", "shell_exec", "scratch_write"]
  }

Changes:
- model_registry.py: get_role_config() returns system_append + tools
- context_loader.py: role_append param appended as "--- Role Context ---"
- tools/__init__.py: get_tools_for_role/get_openai_tools_for_role accept
  optional tool_list and intersect with access-level filter
- orchestrator_engine.py: tool_list threaded through run/resume/checkpoint
- openai_orchestrator.py: tool_list threaded through run/resume/checkpoint;
  _build_client now calls get_openai_tools_for_role instead of returning
  unfiltered OPENAI_TOOL_SCHEMAS
- routers/orchestrator.py: pulls role_cfg for chat_role, passes both
  role_append and tool_list to context loader and engine
