Fix StreamCancelFn type definition

[stevenvo]

Summary

Fixes build errors introduced in #2709 by correcting the StreamCancelFn type definition.

Build Errors

pkg/wshrpc/wshclient/wshclientutil.go:66:24: cannot use func(ctx context.Context) error 
as func() value in assignment

pkg/web/web.go:255:59: cannot use rpcOpts.StreamCancelFn (variable of type func()) 
as func(context.Context) error value in argument

Root Cause

StreamCancelFn was defined as func() in wshrpctypes.go:376, but is actually used throughout the codebase as func(context.Context) error:

• In web.go:276: streamCancelFn(ctx) - called with context parameter
• In wshclientutil.go:67: Returns error from reqHandler.SendCancel(ctx)

Fix

Correct the type definition to match actual usage:

// Before:
StreamCancelFn func() `json:"-"`

// After:
StreamCancelFn func(context.Context) error `json:"-"`

Files Changed

• pkg/wshrpc/wshrpctypes.go - Corrected type definition

Testing

Build now succeeds without type errors.
