ConfigureScope data ignored by captures

Medium Severity

ConfigureScope still writes to the hub scope, but the migrated capture helpers now apply GlobalScope or a context scope. Tags, user data, and event processors set this way are no longer attached to the captured events.

Bug: The call to sentry.AddBreadcrumb in the example code provides two arguments, but the function signature only expects one, causing a compilation error.
_{Severity: MEDIUM}

Suggested Fix

Update the calls to sentry.AddBreadcrumb in _examples/feature-showcase/main.go to match the function's signature by removing the first argument, context.Background(). The call should only pass the *sentry.Breadcrumb struct.

Prompt for AI Agent

Review the code at the location below. A potential bug has been identified by an AI
agent. Verify if this is a real issue. If it is, propose a fix; if not, explain why it's
not valid.

Location: _examples/feature-showcase/main.go#L73-L75

Potential issue: The example code in `_examples/feature-showcase/main.go` calls
`sentry.AddBreadcrumb` with two arguments, `context.Background()` and a
`*sentry.Breadcrumb`. However, the actual function signature for `sentry.AddBreadcrumb`
in `sentry.go` only accepts a single argument: `breadcrumb *Breadcrumb`. This mismatch
between the function call and its definition will cause a compilation error, preventing
the example from being built.

Also affects:

• _examples/feature-showcase/main.go:78~80
• _examples/feature-showcase/main.go:82~84
