"""Tool handlers and schemas for the FCPXML MCP server, split by category.

server.py is the composition root: it imports each module's TOOLS/HANDLERS
and concatenates them for list_tools()/TOOL_HANDLERS. Each module here owns
one category (see Engine/docs/03_SERVER_TOOLS.md) — its Tool() schemas and
handle_<name> functions live together, so a tool's contract and its
implementation are never in different files.
