"""Register OpenFang Hands as MCP tools in Timmy's tool registry.

Each OpenFang Hand becomes a callable MCP tool that personas can use
during task execution.  The mapping ensures the right personas get
access to the right hands:

    Mace (Security)  → collector (OSINT), browser
    Seer (Analytics) → predictor, researcher
    Echo (Research)  → researcher, browser, collector
    Helm (DevOps)    → browser
    Lead hand        → available to all personas via direct request

Call ``register_openfang_tools()`` during app startup (after config
is loaded) to populate the tool registry.
