Add timeout middleware for clients

[salman1993]

• make TransportHandle a generic service so that we can add middlewares like Timeout
• sadly, i had to revert to make McpClientTrait - or else there was no easy way to create a collection of clients (other option was an enum that brances over the different clients but that's more work)

Verified timeout with a local gdrive-mcp-server that has invalid credentials, on v1.0 goose session hangs indefinitely when waiting for a response.

On this branch it exits out:

Error starting reply stream: Failed a client call to an MCP server

The underlying error isn't clear so I think we should at least update https://github.com/block/goose/blob/v1.0/crates/goose/src/agents/system.rs#L10-L11

To include the error:

#[error("Failed a client call to an MCP server: {0}")]
Client(#[from] ClientError),

To give us the following, which is verbose, but provides some detail:
