Elysia events report as sentry.javascript.bun #24045

Running under both node and bun, with the built @sentry/elysia:

sdk: {"name":"sentry.javascript.bun","version":"10.67.0",
      "packages":[{"name":"npm:@sentry/bun","version":"10.67.0"}]}

sentry.javascript.elysia never appears. packages/elysia/src/sdk.ts:44 copies userOptions into options before calling applySdkMetadata(userOptions, 'elysia', ...). When userOptions._metadata is undefined, applySdkMetadata creates a fresh _metadata on userOptions, which the already-made copy does not have. initBun(options) then applies its own 'bun' metadata to the copy.

The Elysia SDK is invisible in SDK adoption telemetry, and support cannot tell Elysia reports from plain Bun ones.

Work item. Call applySdkMetadata(options, ...) on the copy, or move the call above the spread. One-line fix. Add an assertion to packages/elysia/test that event.sdk.name === 'sentry.javascript.elysia'.

Prior art the identical bug was already found and fixed one package over: #15458/#15459 "fix(bun): Includes correct sdk metadata". That PR also added the SDK-metadata assertion to the Bun tests, which is the test to copy here.
