Introduce aegis_gitea_mcp.registry as the single name->handler source of truth consumed by every transport adapter, moving TOOL_HANDLERS out of the FastAPI server module. Add aegis_gitea_mcp.errors.ToolError so core handlers no longer import fastapi.HTTPException; raw_tools now raises ToolError and the HTTP adapter maps it back to HTTPException, preserving status codes and audit behavior. Add a subprocess boundary test asserting the core imports without pulling in fastapi/uvicorn/starlette. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""Lock the transport-agnostic core boundary.
|
|
|
|
The core (tool registry, Gitea client, policy, audit, config, request context,
|
|
tools) must import cleanly without dragging in the web stack. If a stray
|
|
``import fastapi`` creeps back into a core module, the local stdio package would
|
|
gain a needless heavy dependency and the ``[server]`` extra split would leak.
|
|
|
|
The check runs in a subprocess because, within the pytest process, FastAPI is
|
|
already imported by the server tests — so ``'fastapi' in sys.modules`` would be
|
|
true regardless. A clean interpreter is the only reliable probe.
