Raised when a feature is configured whose optional dependency is not
compiled into the current build of :conduit_mcp.
Several ConduitMCP modules are wrapped in if Code.ensure_loaded?(Dep)
guards, which is conditional compilation: whether the module exists is
decided once, when :conduit_mcp itself is compiled inside the consuming
project's _build. Mix does not recompile an already-built dependency when
the consumer later adds one of its optional deps, so adding :joken to
mix.exs is not by itself enough — mix deps.compile conduit_mcp --force
is required.
The message therefore always names both the missing dependency and the rebuild command.
