"""Public facade for the AI tool layer.

Importing this module registers all built-in tools (via
``backend.tools.service``) and re-exports the public API. Consumers (agent
loop, MCP server, tests) should import from here rather than from individual
submodules.

Note: ObsiGate uses implicit namespace packages (no tracked ``__init__.py``,
which ``.gitignore`` excludes via ``_*.py``), hence this explicit facade.
