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>

"""Transport-agnostic error types raised by the core.

Core tool handlers and the authorization layer must not depend on the web stack

(FastAPI). They raise :class:`ToolError` carrying an advisory HTTP status code;
|
|
each transport adapter maps it to its own wire format (the HTTP adapter to
|
|
``fastapi.HTTPException``, the stdio adapter to an MCP error). This keeps the
|
|
core importable without FastAPI installed.
